Question

100 POINTS AND BRAINLIST

Answer 1

X = 55.71 degrees

sin(β) = b / c so β = arcsin(b / c) (inverse sine)
cos(β) = a / c so β = arccos(a / c) (inverse cosine)
tan(β) = b / a so β = arctan(b / a) (inverse tangent)
cot(β) = a / b so β = arccot(a / b) (inverse cotangent) :)

Answer 2

Answer:

$\sf x= 55.7$

using tan rule:

$\sf tan(x)= \dfrac{opposite}{adjacent}$

using the formula:

$\sf tan(x)= \dfrac{22}{15}$

$\sf x= tan^{-1}(\dfrac{22}{15})$

$\sf x= 55.7$
