Answer:
it's answer is C. .80
Step-by-step explanation:
With reference angle A
base (b) = 8
Hypotenuse (h) = 10
Now
Cosine A
= b / h
= 8 / 10
= 0.8
Use Soh Cah Toa. Soh(sin) is the Opposite side divided by the Hypotenuse side so in this case 21/20. Since we need the angle here we would use the inverse of sin. Your equation is Sin(x)=Opposite/Hypotenuse=21/20=1.05
Now solve sin(x)=1.05
Re-arange into
X=sin^-1 (1.05) but since you can’t have a inverse sin of a number more than one it is inconclusive or no answer
