Question

Evaluate the diagram below.

find the values of x and y.

Answer 1

x = 22 degrees.

y = 40 degrees.

Explanation:

The inside angles add up to 180 degrees, therefore:

6x + 4x - 40 = 180

10x = 180 + 40 = 220

x = 22 degrees

In the same way:

3y + y + 20 = 180

4y = 160

y = 40 degrees.
