First you add 3+6, then take 9 and multiply by 2 which is 18, the do 26-18 which is 8×3=24.
12×3=36-12=24.
So 24=24
Your answer is A.
Step-by-step explanation:
use trigonometry ratios
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides
Answer:
w=14.70
Step-by-step explanation:
7^2 = 6^2 + 9^2 - 2(6)(9)cos(m)
-68 = 2(6)(9)cos(m)
cos(m) = -0.6296
m = arcos ( -0.6296)
m = 129.0 degrees
