Question

in the figure find value of y²​

Answer 1

$\LARGE{ \underline{\underline{ \pink{ \bf{ANSWER}}}}}$

y² = 18°

Step-by-step explanation:

We know that

• $\implies$5y²+ 3y² + 2y² = 180° [Linear Pair]

• $\implies$Add the y² terms

• $\implies$Here the y² terms are 5y², 3y²,2y²

• $\implies$So, 5y² + 3y² + 2y² = (5 + 3 + 2)y²

• $\implies$10y² = 180°

• $\implies$y² = 180 ÷ 10

• $\implies$y² = 18°
