Answer:
Step-by-step explanation:
since A and W are complementary, use 180 - 117 to find A. You get 63
since C and X are complementary, use 180 - 82 to find A. You get 98
all interior angles of a triangle add up to 180 so you can use what you have now to find B. B is 19
subtract B from 180 to find Y. Y is 161.
The expression would be $0.20 x f. Once you figure out what the 'f' variable stands for, you have to multiply it by $0.20, and you will have your answer.
Step-by-step explanation:
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
with the sides being opposite to the angles.
so,
14/sin(80) = x/sin(60)
x = 14×sin(60)/sin(80) ≈ 12.3cm
