X =12

Explanation:

Supplementary Angels means the angles are added up to 180 degrees.

So , <1 + <2 = 180

Given that,

<1 = 2x +6

Now lets find the size of <2.

We know that,

Angles in a Straight line is also added up to 180 degrees.

So,

<2+ < 3 = 180

Let's Solve.


< 2 + < 3 = 180 \\ < 2 +( 3x - 6) = 180 \\ < 2 = 180 - (3x - 6) \\ < 2 = 180 - 3x + 6 \\ < 2 = 186 - 3x

Now we know the size of <2

lets find out the value of x


< 1 + < 2 = 180 \\ 2x + 6 + 186 - 3x = 180 \\ 186 + 6 - 180 = 3x - 2x \\ 12 = x

Let's check whether the answer is correct.

We know that <1 =<3 (Alternative Angles)


< 1 = < 3 \\ 2x + 6 = 3x - 6 \\ 2 * 12 + 6 = 3 * 12 - 6 \\ 24 + 6 = 36 - 6 \\ 30 = 30

Answer is Correct !!!

Hope this helps you...

Have a nice day
