I believe 60 degree is your answer
Answer:
9^2= 81, √25= 5, 21^2= 441, √4= 2, √144= 12, 16^2= 256, √625= 25, (-11)^2=121
Answer: a= -18/2
Step-by-step explanation:
2a + 2x3 = -12
2a + 6 = -12
2a + 6 - 6 = -12 - 6 ( subtract 6 from both sides)
2a = -18 (Divide 2 by both sides)
a= -18/2
Answer:
0.8
Step-by-step explanation:
cos z = 8/10 = 0.8
Answer:
Step-by-step explanation:
A. 4^5*4^5 = 4^(5+5) = 4^10 ≠ 4^15
B. (5^4)^5 = 5^(4*5) = 5^20
C. 3^1*3^0 = 3^(1+0) = 3^1 ≠ 3^0
D. 6^20/6^10 = 6^(20 - 10) = 6^10 ≠ 6^2
