Question

4. If 2y and (5y + 40) are supplements of each other they find y?​

Answer 1

${\large{\cal{\red{ANSWER:}}}}$

To Solve:

• Find y

Solⁿ:

• The sum of the angles is 180° , those angles are Supplementary Angles.

$2y + 5y + 40 = 180 \\ \\ 7y + 40 = 180 \\ \\ 7y = 180 - 40 \\ \\ 7y = 140 \\ \\ y = \: { \cancel{ \frac{140}{7}}} \\ \\ { \boxed{ \pink{y = 20}}}$

More To Get:

The Original Angles are:

2y = 2(20) = 40°

5y + 40

5(20) + 40

100 + 40

140°

= 40°, 140°
