Does anybody know this one? 40= 15 - 9x- 2

Step-by-step explanation:

Simplifying 40 = 15 + -9x + -2

Reorder the terms: 40 = 15 + -2 + -9x

Combine like terms: 15 + -2 = 13 40 = 13 + -9x

Solving 40 = 13 + -9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9x' to each side of the equation. 40 + 9x = 13 + -9x + 9x

Combine like terms: -9x + 9x = 0 40 + 9x = 13 + 0 40 + 9x = 13

Add '-40' to each side of the equation. 40 + -40 + 9x = 13 + -40

Combine like terms: 40 + -40 = 0 0 + 9x = 13 + -40 9x = 13 + -40

Combine like terms: 13 + -40 = -27 9x = -27

Divide each side by '9'. x = -3

Simplifying x = -3

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°
