Answer:

( 2 x + 20 )° + ( x +40 )° = 180°

Step-by-step explanation:

They both angles are on straight line so , its supplementary angles and we know that sum of angles of supplementary angle is 180°.

( 2 x + 20 )° + ( x +40 )° = 180°

Can someone answer this if you don’t mind

4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.

Thus, 11x - 18 = 180 degrees.

Combining like terms, 11x = 198, and x = 18.

The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
