Answer:

x=-4

Step-by-step explanation:

-5 ( x - 1 ) - x + 1 = -18

-5x+5-x+1=-18

6x+6=-18 <- -6 from both sides

6x=-24 <- divide 6 by both sides

x=-4

combine like terms

-6x+6=-18

subtract 6 from both sides

-6x=-24

divide both sides by -6

x=4

Find the value of x, y, and z.

Answer:

x = 61°

y = 61°

z = 58°

Step-by-step explanation:

In the given triangle, measures of two sides are equal. So, measures of angles opposite to them are also equal.

Therefore,

$x + x + 58 \degree = 180 \degree \\ \\ 2x = 180 \degree - 58 \degree \\ \\ 2x = 122 \degree \\ \\ x = \frac{122 \degree}{2} \\ \\ x = 61\degree \\ \\ y = 61\degree \\ ( \angle s \: in \: the \: alternate \: segment) \\ \\ z = 58\degree \\ ( \angle s \: in \: the \: alternate \: segment) \\$
