1680/61c2 Step-by-step explanation:
Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
cos(x) = 
cos(x) = 
x = 
x = 25.84
x ≈ 25.8°
12). By applying tangent rule in the given triangle,
tan(x) = 
tan(x) = 
x = 
x = 67.29°
x ≈ 67.3°
They are proportional. If you divide 6/36 by 6 on the numerator and the denominator, you get the same fraction of 1.6.
