Step-by-step explanation:
The angle relationship is vertically opposite angles.
so
x = 77°
The area of a triangle can be found by multiplying the base and the height, and dividing the product by 2.
So, 10*8=80
80/2=40 in^2
Then, the triangle on the left:
10*12=120
120/2=60 in^2
Add up the areas
40 in^2+60 in^2=100 in^2
