Answer:
triangular prism
Step-by-step explanation:
Answer:
25
Step-by-step explanation:
Those parallel lines tell us our triangles are similar. So that means the corresponding sides are proportional.
So we have that x corresponds to x+15 and
40 corresponds to 24+40.
So we have this proportion to solve:

Let's simplify what we can:

Cross multiply:

Multiply/distribute:

Subtract 40x on both sides:

Divide both sides by 24:

x=25
87b-179+957/87 = 180
33b12 = 1584
b2+120 = 128
51b - 24 = 180
So the answer are the first one and the last one :)))
