Answer: y = 23 x = 28

Explanation:

First find the value of y.

The angle (5y -4) and 3y forms a straight line which means that if you add them together they will equal 180 degrees. Add them and set them equation to 180 to solve for y.

5y-4 + 3y = 180

8y -4 = 180

+4 +4

8y = 184

y= 23

Since y is equal to 23, then input y into the expression (5y-4) to find the main angle value and then add it with the angle (2x+13) to equal to 180 degrees because they also form a straight angle.

5(23) - 4

115 - 4 = 111

111 + (2x + 13) = 180

124 + 2x = 180

-124 -124

2x = 56

x = 28

x is equal to 28 degrees.

Check.

111 + 2(28) + 13 = 180

111 + 56 + 13 = 180

180 = 180
