Question

If two angles of measure (x+27°) (3x-39°) are supplementary find x

Answer 1

Answer:

if this are supplement

Step-by-step explanation:

x+27+3x-39=180

4x-12=180

4x=192

x=48

Answer 2

Answer:

48°

Step-by-step explanation:

Concept= Supplementary Angles

Given= The angle measures.

To find=  The variable x.

Explanation=

We have been given that if two angles of measure (x+27°) and (3x-39°) are supplementary find x.

Supplementary angle means that if one is x° the another is 180° -x°.

Therefore the sum of two angles which are supplementary the sum of two angles is 180°.

Given two angles (x+27°) and (3x-39°) .

Therefore the sum of (x+27°) and (3x-39°)  is 180°.

=> (x+27°) + (3x-39°) = 180°

=> 4x -12° = 180°

=> 4x = (180+12)°

=> 4x = 192°

=> x= 192°/4

=> x= 48°.

Therefore the value of x is 48°.
