Answer:
a = 4, x = 1
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
WX = YZ , that is
a² + 5a = 5a + 16 ( subtract 5a from both sides )
a² = 16 ( take the square root of both sides )
a = ± [tex]\sqrt{16}[/tex] = ± 4
Since a > 0 , then a = 4
Also
XY = WZ , that is
x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Since x > 0 , then x = 1

What's the area of the composite figure below ?
Answer:
31.13
Step-by-step explanation:
If you look carefully, you will find a semicircle and a triangle.
The total area is =
[tex]\frac{\pi r^{2}}{2} + \frac{1}{2} \times base \times height\\[/tex]
r = 4 - 0 = 4base = |-4-0 | = 4height = 14 - 9 = 5So if we put the values:

Answer:
x=33
Step-by-step explanation:
1) write the equation: 180=90+(x+15)+(x+9)
2) subtract 90 on both sides and add x+15 and x+9 together: 90=2x+24
3) subtract 24 from both sides: 66=2x
4) divide both sides by 2: x=33

Answer this please...........
okay lets begin with the first part of it which is tan
sinx=p/h -----> some people have
cosx=b/h ----> curly brown hair
tanx=p/b -----> through proper brushing
an easy way to remember the ratios ^
we have sin and cos so we can say that the h=41 b= 40 and p is 9
so tan will be [tex]tanA=\frac{9}{40}[/tex]
now csc sec and cot are reciprocals of sin cos and tan
so sinA is 9/41 cscA will be 41/9
cosA is 40/41 secA will be 41/40
tanA is 40/9 cotA will be 40/0

Which graph represents the function f(x) = 4|x|?
Which graph represents the function f(x) = 4|x|?
It looks like a "V" going straight up from 0, and hits both 4 and -4 y while going up perfectly
The graph opens upward, and it has a vertex of (0,0)
What is vertex?The vertex of an equation is the minimum or the maximum point on the graph of the equation
The equation of the graph is given as:
[tex]f(x) = 4|x|[/tex]
The above equation represents an absolute value function
An absolute value function is represented as:
[tex]f(x) = a|x -h| + k[/tex]
So, by comparison, we have:
[tex]a = 4[/tex]
[tex]h = 0[/tex]
[tex]k = 0[/tex]
This means that the graph opens upward, and it has a vertex of (0,0)
See attachment for the graph of [tex]f(x) = 4|x|[/tex]

if ?/100 = 0.2 then ? =
Answer:
20
Step-by-step explanation:
x / 100 = 0.2
Multiply both sides by 100 to isolate x. 100 x 0.2 = 20
In the given expression the missing term is 20.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.
The given expression is:
?/100 = 0.2
Then we have to find out the missing term.
Let the missing term is x
Therefore, we can write,
x/100 = 0.2
Multiply 100 on both sides we get,
x = 0.2 x 100
x = 20
Hence,
The missing term is 20.

88=(−x+3)8 , please? step by step? thanks <33
Answer:
-8
Step-by-step explanation:
88=(-x+3)8
88= -8x+24
88-24= -8x
64= - 8x
- x= 64/8
-x=8
x= -8
88 = ( -x + 3) x 8
88 = (3-x) x 8
8= 8 (3-x)
88/8 = 3 - x
11 - 3 = -x
8 = -x
-8 = x
x = -8

Imagine that you need to create a scale drawing of this sign. The scale drawing will
be used to create a mold that will be used to manufacture the sign. Use the grid to
make a scale drawing of this sign. Include a key to show the relationship between
the dimensions in the scale drawing and the dimensions of the actual sign. Label all
sides in the scale drawing. Show your work. (3 points)
A scale drawing with a 1: 0,8 scale will have sides that measure 2.24, 1.6, and 3.2.
What is a scale drawing?A scale drawing refers to a drawing that has been made bigger or smaller but preserves the proportions of a drawing.
How to make the scale drawing of the sign?The first step is to decide the scale. In this case, the best scale is 1:0.8, which means the new drawing is 0.2 smaller. This scale is ideal because this sign is slightly bigger than regular signs.
Draw the sign by multiplying each side by the scale (0,8).

Side YQ and side XP are altitudes to the congruent sides of isosceles triangle WXY. Keisha is going to prove side YQ ≅ side XP by showing they are congruent parts of the congruent triangles QXY and PYX.
By the triangle congruence we can use the SSA method to prove the base angles are congruent.
What do you mean by congruent triangles?If two or more triangles are congruent, it depends on how big their sides and angles are. The three sides and three angles of a triangle determine its size and shape, accordingly. Two triangles are said to be congruent if the pairings of respective sides and corresponding angles are equal.
These are exactly the same size and shape. There are several different congruence conditions that triangles might meet.
In the figure given,
It is necessary to demonstrate the congruence of the triangles PYX and QXY.
Both triangles have the same XY base.
PX must equal QY because the lines PX and QY are perpendicular on congruent sides.
Angles PYX and QXY are equal since the axiom "Angles opposed to equal sides are equal" states that they are.
As a result, it can be shown that the two triangles PYX and QXY have two sides and an equal angle.
As a result, using SSA criteria, the two triangles will be congruent.
Hence, option C is the best one.
