Question

Find the uknown angle.

Answer 1

Answer:

angVSU = 42⁰

Step-by-step explanation:

ang.UST = angVUS ( alternative angles )

so angVUS = 42⁰

NOW

angVUS = angVSU ( angles opp. to equal side of a )

so req. angVSU = 42°

Answer 2

Answer:

Angle VSU=42⁰

Step-by-step explanation:

RU is parallel to ST (RSTU is a trapezium)

Therefore, VU is parallel to ST

VS=VU

Therefore, angle VSU=angle VUS (angles opposite to equal sides in a triangle)

angle VUS=angle UST (alternate angles are equal)

Thus, angle VUS=42⁰

Therefore, angle VSU=42⁰ (angle VSU= angle VUS)
