Question

6a) Determine the measure of each angle and the triangle.

Answer 1

Explanation:

5x = 90

2x = 36

3x = 54

And is a rectangle triangle.

Answer 2

x = 18

Explanation:

If we're to find for x.

then interior angle of triangle having 3 side

=Sum of interior angle

`= (n - 2)180`

`(3 - 2)180 \\ = 1 * 180 \\ = 180`

therefore the value for x

2x + 5x + 3x =180

10x = 180

10x/10 = 180/10

x = 18.
