Find the value of X that makes the drawing below true (drawing is not to scale)

“ x = _”

*answer quick pls*

Given:

Given that the angles (12y + 5)° and (18y - 7)° are vertical angles.

Also, given the other angle is (3x + 1)°

We need to determine the value of x.

Value of y:

Since, the angles (12y + 5)° and (18y - 7)° are vertical angles, then they must be congruent.

Thus, we have;

Thus, the value of y is 2.

Value of x:

From the figure, it is obvious that the angles (18y - 7)° and (3x + 1)° are linear pairs.

Thus, we have;

Substituting y = 2, we get;

Thus, the value of x is 50.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
