Answer:
D) 73.5º
Step-by-step explanation:
Law of sines
sinQ/15 =sin50.1/12
multiply both sides by 15
sinQ = sin50.1/12 * 15
sinQ = 0.958956439769124
Q = arcsin0.958956439769124
Q = 73.5º

Answer:
6) B. q^18
7) C. 1/1296q^24
8) A. -12/5
Step-by-step explanation:
6. (q^9)^2
= q^(9*2)
= q^18
Answer
B. q^18
7.(6q^6)^-4
= 1/(6q^6)^4
= 1 / 1296q^24
Answer
C. 1/1296q^24
8. What is the value of 12x^-3 y^-1 for x = -1 and y = 5?
12x^-3 y^-1
= 12/x^3y
= 12 / (-1)^3 (5)
= 12/-5
= - 12/5
Answer
A. -12/5
