Answer:

Step-by-step explanation:

∠PQY + ∠RQY = 180 {STRAIGHT LINE}

∠PQY + 118 = 180

∠PQY = 180 - 118

∠PQY = 62

PY = QY

Therefore, ∠QPY = ∠PQY {angles opposite to equal sides are equal}

∠QPY = 62

PR // XZ & YP is transversal

∠XYP = ∠QPY {Alternate interior angles are equal}

a = 62°

Answer:

Step-by-step explanation:

The prism shown is a triangular prism

The volume of a triangular prism can be found by multiplying the area of the base ( which is a triangle ) by the length of the prism ( which is 10 feet )

First let's find the area of the base.

To find the area of a triangle we use this formula $A=\frac{bh}{2}$

where b = base length and h = height

The base length is 6ft and the height is 4ft.

Using these dimensions we plug in the values into the formula

$\frac{4*6}{2} \\4*6=24\\\frac{24}{2} =12$

So the area of the base is 12ft²

Finally to find the volume we multiply the area of the base by the length of the prism

12 * 10 = 120

Hence, the volume of the prism is 120ft³
