Question

if (3x+2) and (3x+4) are supplementary angles find value of x
​

Answer 1

Answer:

Angles 91º and 89º

x = 29

Step-by-step explanation:

Supplementary angles always add up to 180º.

So, the sum of (3x+2) and (3x+4) equals to 180º.

Solving it-

3x + 2 + 3x + 4 = 180

    6x +6           = 180

       6x              = 174

        x               = 174/6

        x               = 29

3x + 2 = 89º

3x + 4 = 91º

Adding the two angles will result the sum as 180º

Therefore, your answer is 29.

Hope this helps...

Answer 2

Answer:

29°

Step-by-step explanation:

Sum of supplementary angles=180°

==>3x+2+3x+4=180°

==>6x+6=180°

==>6x=174

==>x=29°
