Answer:
Step-by-step explanation:
Tan 70 = 16/x
x = 16/tan70
x = 5.824 to the nearest thousandth
tan 41 = 16 / (x + y)
tan 41 = 16 /(5.8235 + y)
tan41(5.8235 + y) = 16
5.8235 + y = 16/ tan41
y = (16/ tan41) - 5.8235
y = 12.582 to the nearest thousandth
solve for y 3x+6y=30
Answer:
the answer= y=5−x/2
Answer: [tex]y=-\frac{1}{2} x+5[/tex]
Step-by-step explanation:
We need to isolate y by itself
Step 1) Subtract 3x from both sides
[tex]3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x[/tex]
Step 2) Divide both sides by 6 to isolate y
[tex]6y=30-3x\\\frac{6y}{6} =\frac{30}{6}-\frac{3x}{6} \\y=5-\frac{1}{2}x[/tex]

Solve the system of equations y = 2x^2 + x – 6 and y = 4
Step-by-step explanation:
Substitute y = 4 into the first equation:
[tex]4=2x^2+x-6[/tex]
Subtract 4 from both sides:
[tex]2x^2+x-10=0[/tex]
We can factor in order to find values of x.
Factor the equation:
[tex]2x^2+x-10=0[/tex]
Factors of 10 we'll use:
5 and 2.
[tex](2x+5)(x-2)=0[/tex]
Set the parentheses equal to 0 then find the values of x:
[tex](2x+5)=0[/tex]
[tex]x=-2\frac{1}{2}[/tex]
[tex](x-2)=0[/tex]
[tex]x=2[/tex]

A figure is comprised of 2 rectangles. The first rectangle has a length of 10.5 centimeters and width of 15.5 centimeters. The second rectangle has a length of 18 centimeters and width of 11.5 centimeters.
135 centimeters squared
207 centimeters squared
249 centimeters squared
279 centimeters squared
Answer:
249 centimeters squared
Step-by-step Explanation:
The area of the rectangle: l x w, where l is the length and w is the width.
= 15.5 x 18
= 279
Area of the smaller rectangle: l x w, where l is the length and w is the width.
= 4 x 7.5
= 30
We do not need this 30.
Area of the shaded region:
= 279 - 30
= 249 cm²

What is Isosceles Triangle ?An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:
It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.We have a Triangle.
Then, using Isosceles Triangle Theorem
Angles opposite an isosceles triangle's equal sides are also equal.
According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.
So, x= 42 degree.

please help, thank you very much to whoever helps.
Answer:
x = 20
B = 92°
C = 40°
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°
⇒ A + B + C = 180°
⇒ 48 + (6x - 28) + 2x = 180
⇒ 48 + 6x - 28 + 2x = 180
⇒ 48 - 28 + 6x + 2x = 180
⇒ 20 + 8x = 180
⇒ 8x = 180 - 20
⇒ 8x = 160
⇒ x = 160 ÷ 8
⇒ x = 20
Now we have found x, simply substitute this into the expressions for angles B and C:
B = 6(20) - 28
= 120 - 28
= 92°
C = 2(20)
= 40°
Answer:
x = 20
m<B = 92
m<C = 40
(m<A = 48)
Step-by-step explanation:
triangles are 180 degrees
add up the sides
48 + (6x-28) + 2x
8x + 20 = 180
8x = 160
x = 20
put 20 where the x is for B and C
B.
6(20)-28 =
120 - 28 =
92
C.
2(20) =

solve for x
x - 1 2 (8 - x) = x + 3(4 - x) - x
Answer:
The correct answer is x = 32/9
Step-by-step explanation:
You must multiply the given numbers from left to right, resulting in:
x - 4 + x/2 = x + 12 - 3x - x
Then, by combining phrases on both sides that are similar, we get:
(3/2)x - 4 = -3x + 12
By adding 4 to both sides of the equation, it becomes:
(3/2)x = -3x + 16, or
3/2)x + (6/2)x = 16, which may be written as:
3x + 6x = 32, or 9x = 32
Therefore, the answer is x = 32/9

Whats the was i could solve this
Answer:
so let's see buddy....
Step-by-step explanation:
look at that angle having 45, zed (Z) angles are equal, which means the bottom left inside the triangle is also 45°.
now sum of angles in a triangle is 180°...
so we add up all the angles and equal them to 180° but an angle is missing, let's name it Y°.
so...
96°+45°+Y°=180°
101°+Y°=180°
Y°=180°–101°
Y°=79°
to find x, sum of angles in a straight line is 90°
so we subtract 79 from 90
x°= 11

2. a/c 5. c/a
3. b/a 6. a/b
Step-by-step explanation:
sin theta = opposite/hypotenuse = b/c
cos theta = adjacent/hypotenuse = a/c
tan theta= opposite/adjacent = b/a
For the rest, you just flip it:
csc theta = c/b
sec theta = c/a
