Answer:
<PQS = 47
<SQR = 43
Explanation:
A right angle equals 90°.
7x + 145 + 6x + 127 = 90 Combine like terms
13x + 272 = 90 Subtract 272 from both sides
13x = 90 - 272
13x = -182 Divide both sides by 13
x = -14
Substitute -14 for x
<PQS
7x + 145
7(-14) + 145
-98 + 145
47
<SQR
6x + 127
6(-14) + 127
43
43 + 47 = 90
