Evaluate the following expressions. your answer must be an angle −π/2≤θ≤π in radians, written as a multiple of π. note that π is already provided in the answer so you simply have to fill in the appropriate multiple. e. g. if the answer is π/2 you should enter 1/2. do not use decimal answers. write the answer as a fraction or integer. sin-1(sin((−5π/6)) =πsin-1(sin(5π/3))=πcos-1(cos(2π/3) )=πcos-1(cos(−7π/4))=π

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
