Question

What is the measurement

Answer 1

X=135 degrees

Explanation:

the total interior angle of a triangle is 180.

To work this out you would first add the interior angles of B which is 69 and the interior angle of C which is 66, which gives you 135.

The next step is to minus 135 from 180, which gives you 45. This is because the total interior angle of a triangle is 180.

Then to work out the angle of x you would minus 45 from `180, which gives you 135. This is because the total angle in a straight line is 180 degrees.

1) Add the angles of 69 and 66.

`69+66=135\\`

2) Minus 135 from 180.

`180-135=45`

3) Minus 180 from 45.

`180-45=135 degrees`
