Math help ASAP easy points<br><br> What is the value of Z?<br><br> Enter your answer in the box.
Romashka [77]
<h3>Answer:  23</h3>

The three angles of any triangle always add to 180, so,

z+62+95 = 180

z+157 = 180

z+157-157 = 180-157 .... subtract 157 from both sides

z = 23

As a check,

z+62+95 = 23+62+95 = 180

so the answer is confirmed.
