Answer:
y = 28°
Step-by-step explanation:
The triangle is a right triangle which has 90 degrees.
The 3x falls under 90 degrees.
So:
→ 2y + 90° + 34° = 180°
→ 2y = 180° - 124°
→ 2y = 56°
→ y = 28°
As we know the volume of a prism is the product of height and base are
H(x)= height, A(x)= Base area
Thus,
When volume = height(base area )
V(x)= A(x) · H(x)
= (x²-2)(5)
= 5(x² -2)
