Step-by-step explanation:
8) 125=x+90° (exterior angle= sum of two opposite interior angle)
x= 35°
9) y=80° ( vertically opposite angle)
x= 180-50-80= 50°.
hope this helps you.
Divide the irregular figure into rectangles
Area of rectangle = l * w
4 * 5 = 20 in^2
5 * 12 = 60 in^2
7 * 11 = 77 in^2
Add them together
20 + 60 + 77 = 157 in^2

2 because if you have a square and draw a diagonal you get two triangles
Answer:

Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

solve for x


Find the angle measurements
