Question

Find the value of x and y in the given figure.
​

Answer 1

$\Huge\bf\underline{\underline{\purple{Answer}}}$

First find the value of y.

Angle sum property of triangle = Sum of all sides.

$\large\bf\implies{\underline{\green{30 \: + \: 90 \: + \: y = 180}}}$

$\large\bf\implies{\underline{\green{120 + y = 180}}}$

$\large\bf\implies{\underline{\green{y = 180 - 120 = 60}}}$

$\large\bf\implies{\underline{\red{y = 60}}}$

X = Sum of opposite side if triangle .

$\large\bf\implies{\underline{\blue{x = 30 + 90}}}$

$\large\bf\implies{\underline{\orange{x = 120}}}$

Answer 2

$\huge\bf\underbrace\red{Answer}$

First find the value of y.

Angle sum property of triangle = Sum of all sides.

⟹ 30 + 90 + y = 180

⟹ 120 + y = 180

⟹ y = 180 − 120 = 60

⟹ y = 60

X = Sum of opposite side if triangle .

⟹ x = 30 + 90

⟹ x=120
