Answer:
y = 5
x = 5
Step-by-step explanation:
find the complete question in the attached image
the angle opposite 5y is also 5y. this is because alternate angles are equal
180 = 155 + 5y
5y = 180 - 155
5y = 25
y = 5
the sum of 5y and 13x is equal to 90
this is because the sum of angle on a straight line is equal to 180 and one of the angle on the straight line is already equal to 90 . so, 90 (180 - 90)
5y + 13x = 90
25 + 13x = 90
13x = 90 - 25
13x = 65
x = 5
