Answer:
212.5
Step-by-step explanation:
For triangles, A = (bh)/2
You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.
Again do 17*15/2, which you get 127.5.
From here subtract 127.5 from 340 and get 212.5
Answer:
adjacent angles
complementary angles
Step-by-step explanation:
vertical angles are across from each other and equal False
adjacent angles are next to each other True
Complementary angles add to 90 degrees ( If next to each other , they form a right angle) True
Supplementary angles. add to 180 degrees, ( if next to each other, they form a straight line) False
Volume of a pyramid = 
Given base is = 140 m
Given height is = 96 m
Volume = 
Hence, volume of pyramid is 4480 m³
