Question

1. find x + y.

Explanation:

Step1: Use the property of linear - pair of angles

A linear - pair of angles sums up to 180°. For the angles 3x and 144°, we have 3x+144 = 180.
3x=180 - 144
3x = 36
x = 12

Step2: Use the property of linear - pair of angles for the other pair

For the angles 2y - 5 and 95°, we have (2y - 5)+95 = 180.
2y+90 = 180
2y=180 - 90
2y = 90
y = 45

Step3: Calculate x + y

x + y=12 + 45
