I'm gonna use c for circle, t for triangle, and s for square
c+t+s=13
t+s=8
c+8=13
c=5
c+t=7
t=2
s=6
circle is 5, triangle is 2, and square is 6
The value of x using the alternate exterior angle theorem is 82°
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An angle is formed from the intersection of two or more lines. Types of angles are<em> acute, obtuse and scalene</em>.
From the diagram:
x = 82° (alternate exterior angles)

Answer:
x = 12
∠A = 144
Step-by-step explanation:
+ We have: ∠A = ∠C (alternate interior)
∠D = ∠C ( vertically opposite angles)
=> ∠A = ∠C (because = ∠C)
=> 10x + 24 = 6x + 72
=> 10x - 6x = 72 - 24
4x = 48
x = 12
+ ∠A = 10x + 24
∠A = 10 x 12 + 24
∠A = 144
