Explanation: According to the image provided, all three angles should be the same. This makes it much easier to solve the problem. It is necessary to remember that a triangle equals a total of 180 degrees. Since there are three angles, we shall divide 180 by three.
180/ 3 = 60
Now we will use 60 to help us solve for the values of x and y.
Step 1 - Step up your equation to find y
y - 10 = 60
Step 2 - Add 10 to both sides of the equation
y - 10 = 60 y - 10 + 10 = 60 + 10 y = 70
So, y = 70
Step 4 - Set up your equation to find x
x + 5 = 60
Step 5 - Subtract 5 from both sides of the equation
