first convert 0.88 to degrees
so arcsin(0.88) = 61.642 degrees
Arcsin on a calculator is sin^-1
then to convert to radians divide degrees by 180 and multiply that by PI
so (61.642/180) x PI = 1.076 radians
Answer:
-5.5
Step-by-step explanation:
Remaining angle = 180-90-60=30
by sine rule
8/sin30 = x/sin90
x = 8/0.5=16
The answer is 2.37 × 10^-3
5/80 × 100 = 25/4 = 6.24%
