Question

Write the supplement angle of (y-30)°.​

Answer 1

Step-by-step explanation:

Each angle is called the supplement of the other. Example, 30° and 150° are supplementary angles, because 30° + 150° = 180°. Clearly, 30° is the supplement of 150° and 150° is the supplement of 30°. Thus, the supplement of angle 105° = 180° - 105° = 75°.

Answer 2

Step-by-step explanation:

Given angle is = ( y- 30 )

Formula of supplement angle = 180 - Given angle

= 180 - ( y- 30 )

= 180 -y +30

= 180 +30 -y

= 210 -y

supplement angle = ( 210 - y)
