Answer:
102°
Step-by-step explanation:
∠PQR = ∠PQS + ∠SQR
12x - 6 = 16 + 9x + 17
3x = 27
x = 9
∠PQR = 102°

the the negative angle is -(2π-π/4)= -\frac{7 \pi }{4}
Answer:
7/20
Step-by-step explanation:
To add fractions, the first step is to get a common denominator
1/4 + 1/10
The common denominator is 20
1/4 *5/5 = 5/20
1/10 *2/2 = 2/20
5/20 + 2/20 = 7/20
