Answer:
m∠F = 45°
because
Corresponding
Parts of
Congruent
Triangles are
b. 36
Step-by-step explanation:
You have to use Pythagorean theorem. A squared + b squared = c squared.
a=12 12^2 (12 squared)= 144
b=9 9^2 (9 squared)= 81
144+81=225
Then you find the square root of 225 which is 15. Since you have the length for side c.
12+9+15=36
answer: 30 becuase its equal to the other angle
