Answer: 67.8°
Step-by-step explanation:
A quadrilateral's interior angles always add up to 360°.
An equality statement can be set up to satisfy this rule:
103.8+77+111.4+p=360
Collect known values
292.2+p=360
Isolate and solve for p
292.2 (-292.2) +p=360 (-292.2)
p=67.8
Answer:
68.6
Step-by-step explanation:
hello sir / mam!
as the opposite sides of quadrilateral should be 180°
111.4+p=180°
p=180-111.4
p=68.6°
therefore the value of p = 68.6°
hope it helps!

The number 18 in the form of complex numbers will be written as 18 + 0i.
What are complex numbers?Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfies the equation i² = 1.
The given number is 18. The number in the form of a complex number can be written as:-
Complex number = a + bi
Complex number = 18 + 0i
Therefore, the number 18 in the form of complex numbers will be written as 18 + 0i.

Length :

feet
Width :
10

Explanation:
Let the length of the garden be
x
feet.
Therefore, the breadth or width of the garden is
(
x
−
2
)
feet.
So, According to the problem,
x
(
x

)
=

⇒
x

−

x
=
120
⇒

x

[Transposing 120 to the L.H.S]
⇒

x

x
−
120
=

[Breaking

⇒
x
(

)
−

(

)
=
0
[Taking the like terms aside]
⇒
(
x
+
10
)
(
x
−
12
)
=
0
[Completing the factorisation]
We know, When two real quantities are multiplied and the product is zero, then one of them or both of them should be zero.
So, Either
x
+
10
=
0
or
x
−
12
=
0
So,
x
=
−
10
or
12
As
x
indicates length,
x
can't be negative.
So,
x
=
12
.
So, The length of the garden is
12
feet and the width of the garden is
(
12

)
feet =

Tori, Brielle, and Abby, go shopping together. Together they spend $215. Brielle spends twice as much as Tori, and Abby spends one dollar less than three times what Tori spends. How much did each girl spend?
Step-by-step explanation:
Tori + Brielle + Abby = 215
Give Tori spends x.
Brielle ; 2x and Abby ; 3x - 1
so
x + 2x + 3x - 1 = 215
6x - 1 = 215
6x = 216
x = 36
Tori spends $36 Brielle spends $72 and Abby spends $107.

Answer:
The correct choice is option a. -3x^2 + xy + 3x - y + 2
Step-by-step explanation:
(xy + 3x + 2) - (3x^2 + y)
= xy + 3x + 2 - (3x^2 + y)
= xy + 3x + 2 - 3x^2 - y
= -3x^2 + xy + 3x - y + 2
The correct answer of the given choices i think it would be A
two complementary angles are in a ration of 2 3 find the measure of each angle
A complementary angle is 90 degrees. The ratio is 2:3 so the equation would be:
2x+3x=90
5x=90
x=18
One of the angles would be 2(18) or 36 degrees and the other angle would be 3(18) or 54 degrees.
36+54 is equal to 90 degrees so it checks out.

You add a number to (–3) and the sum is negative. List four possible numbers you
might have added and four you could not have added.
Answer:
Four possible numbers
-4
-32
-2
-10
Four numbers that are not possible
100
120
20
10
Step-by-step explanation:
I choose the 4 possible numbers because if you add a negative to a negative, the answer will always be a negative. However if you added a positive like 100 to -3, the answer wouldn't be negative so that's why I chose those numbers.

[tex]\sf 15=2x-9[/tex]
Answer:
x=12
Step by step explanation:
Step by step explanation:Add 9 to both sides :
15 = 2x - 9
15 + 9 = 2x - 9 + 9
Simplify:
24 = 2x
Divide both sides to get the result:
24 = 2x
24/2 = (2x)/2
Result:
