Use the slope formula to find the missing coordinate.
m =
7. T(13, 2), WL,_-5)

WL = 12

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

7 = (-5 -2)/(WL - 13)

Multiply each side by (WL - 13)

7 (WL - 13) = -5-2

7 (WL - 13) = -7

Divide each side by 7

(WL - 13) = -1

Add 13 to each side

WL - 13+13 = -1 +13

WL = 12

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

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°
