The base angles of an isosceles triangle are equal
The base angles are 15 degrees, while the vertex angle is 150 degrees
The base angles are given as:
Base = (6a- 3) and (a + 12)
So, we have:

Collect like terms


Divide both sides by 5

Substitute 3 for a in Base = (6a- 3),



So, the base angle is 15 degrees.
The vertex angle is calculated using:

So, we have:


Hence, the vertex angle is 150 degrees

12.3 meters because of the 10 meters she jumped plus the 2.3 she went down equals 10+2.3=12.3
They are independent because they do not rely on each other.
Given:
Triangular prism.
Base area : 37.4 square yards
height : 5 yards
To find the volume of the ramp based on the given figures, we simply multiply the base area by the height.
Volume = base area * height
V = 37.4 square yards * 5 yards
V = 187 cubic yards.
The volume of the triangular prism-shaped ramp is 187 cubic yards.
