Question

solve for m∠rsu if m∠rst = 143° and m∠ust = 83°. answer attempt 1 out of 3 m∠rsu =

Explanation:

Step1: Identify angle - relationship

We know that $\angle RST=\angle RSU+\angle UST$.

Step2: Rearrange the formula to solve for $\angle RSU$

$\angle RSU=\angle RST - \angle UST$.

Step3: Substitute the given values

Given $\angle RST = 143^{\circ}$ and $\angle UST=83^{\circ}$, then $\angle RSU=143 - 83$.

Step4: Calculate the result

$\angle RSU = 60^{\circ}$.

Answer:

$60$
