Step-by-step explanation:
Trust me. It have a B+ in Geometry
answer is
D. 139 degrees
angle GJI is composed of angles GJH and HJI, so we just need to add those two angles to find the angle measure of angle GJI
91+48=139
It would be sqrt 175
perimeter of triangle: P = l+w+h
9+12+10= 31in.
area of triangle: A=b×h÷2
21 + 21 = 42in^2
