Question

If the angles 2yº and 3yº are supplementary,
find the value of y.​

Answer 1

Answer:

36º

Step-by-step explanation:

2yº & 3yº are supplementary.

∴2yº + 3yº = 180º

⇒ 5yº = 180º

⇒ yº = 180º/5 = 36º

Answer 2

Answer:

Given - 2y° and 3y° are supplementary

To find - value of y

Solution -

We know that if 2 angles are supplementary then its sum is 180°

2y + 3y = 180 °

5y = 180 °

y = 180/ 5

y = 36 °

More to find

2y = 2 × 36

= 72°

3y = 3 × 36

= 108°

Verifying answer

108 + 72 = 180

180 = 180

hence proved.
