Question

find m∠ijs if m∠ijk = 153° and m∠sjk = 125°.

Explanation:

Step1: Identify angle - relationship

We know that $\angle IJK=\angle IJS+\angle SJK$.

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

$\angle IJS=\angle IJK - \angle SJK$.

Step3: Substitute the given values

$\angle IJS=153^{\circ}- 125^{\circ}$.

Step4: Calculate the result

$\angle IJS = 28^{\circ}$.

Answer:

$28^{\circ}$
