The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees. z as the third angle in the small triangle is 180 less than the sum of the other two,
z = 180 - 22 - 102
Answer: 56 degrees
Answer:
56 degrees.
Step-by-step explanation:
x = 180 - (68+78)
= 34 degrees ( as there are 180 degrees in a triangle).
Consider the large right-angled triangle:
z = 180 - (90 + x)
= 180 - (90 + 34)
= 180 - 124
= 56 degrees.

Volume = (base area × height)/3
base area = 96, h = 15
V = (96 × 15)/3
V = 480cubic mm
