<h3><u>Given :-</u></h3>
- Here, we have given one quadrilateral that is quadrilateral ABCD
- We also have given the angles of quadrilateral that is ( 6x + 5)° , ( 9x - 10)° , 80° and a right angle
<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>
Here, we have to find the value of x
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u><u> </u></h3>
We have given quadrilateral ABCD here , whose angles are as follows
- Angle A = ( 6x + 5)°
- Angle B = ( 9x - 10)°
- Angle C = 80°
- Angle D = A right angled triangle
[ The measure of right angled triangle is 90° ]
<u>We </u><u>know </u><u>that</u><u>, </u>
- Sum of the angles of quadrilateral is equal to 360°
<u>That </u><u>is </u>

<u>Subsitute </u><u>the </u><u>required </u><u>values </u>









Hence, The value of x is 13 .

Measure of Angle A




Measure of Angle D




<u>Now</u><u>, </u><u> </u><u>we </u><u>know </u><u>that</u><u>, </u>
- Sum of angles of triangles is equal to 360°
<u>That </u><u>is</u><u>, </u>





Hence, Proved.
Answer:
129 square feet.
Step-by-step explanation:
10x15= total area of the entire wall.
10x15=150
3x7=total area of the door
3x7=21
150-21=total area of just the wall and not the door.
150-21=129
answer: 129 square feet.
OR
15x3=45
7x6=42
7x6=42
45+42+42=129
(if you wanna know how to do this second method lmk and I can attach a photo of exactly how to do it)

The answer is
<h2>

</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-8, 3), (-8,-4)
The midpoint is

We have the final answer as

Answer:
D: 20h + 45 = 165
Step-by-step explanation:
20 for EACH hour means that there's a variable (h) attached to 20 so it has to be 20h
Because of that, we can eliminate choices A and B.
Charges mean that it's ADDED to the price so it has to be 45 PLUS 20h
20h + 45 = 165
