Since its to the tenth power and the exponent is negative all you have to do is move the decimal point two positions back and your new answer is 0.382
Answer:
Y = 59.0°
Step-by-step explanation:
Using the cosine rule in terms of x, y and z
cosY = 
with x = 22, y = 20 and z = 18
cosY = 
= 
=
, thus
Y =
(
) ≈ 59.0° ( to the nearest tenth )
