The plane would pass through opposite sloping faces of the pyramid and through the base; the shape formed is a triangle.
I believe it's the first 3 boxes
13,571.68 cubic feet?? I'm pretty sure
Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.
Thus, lets form an equation:
90 = 5x + 19 + 4x - 1
72 = 9x
x = 9
Thus, the measure of angle B is 64°.
Answer:
x = 15
Step-by-step explanation:
-x = -15
x = -1 × (-15)
