Given the figure, find the values of x and z.

z = 91

x = 11

Step-by-step explanation:

Angle Z is a vertical angle to the 91-degree angle, so they are congruent, or equal.

To solve for x, you can use the equation 91 + 7x + 12 = 180 to solve for x:

91 + 7x + 12 = 180

103 + 7x = 180

7x = 77

x = 11

x = 11, z = 91

Step-by-step explanation:

z = 91. Reason: Vertical angles are equals.

Angles on a straight line add up to 180, so:

(7x + 12) + 91 = 180

7x + 12 + 91 =180

7x + 103 =180

7x = 77

x = 11

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
