Question

<4 and <5 form a linear pair and m<4 = 62. Find m<5.

Answer 1

Well, just use what you know.

You know that a linear pair of angles are supplementary, adding up to 180 deg.

So, if m<4 + m<5 = 180
and
m<4 = 62, what does that leave left for m<5?

Presumably if you are taking geometry, you passed algebra I
