Question

Guys please solve question no 11,12​

Answer 1

Heya

GOOD MORNING!!

11)

Let that angle be x

ACCORDING TO THE QUESTION

( 180 - x ) = 4 ( 90 - x )

=>

180 - 360 = -4x + x

=>

3x = 180

=>

x = 60°

So, the angle is 60°

12)

Let that angle be y

ACCORDING TO THE QUESTION

( 90 - y ) = ( 180 - y )/3

=>

270 - 3y = 180 - y

=>

90 = -y + 3y

=>

2y = 90

=>

y = 45°

So, the angle is 45°

Answer 2

Ans. 11

Let the angle be x

Complement= 90-x

Supplement=4×(90-x) = 360-4x

x+360-4x=180

3x=180

x=60

Therefore the angle is of 60°

Ans. 12

Let the angle be x

It's supplement= 180-x

ATQ, Complement=180-x/3

so, x+180-x/3= 90

2x+180= 90×3

2x= 90

x= 45

Therefore the angle is of 45°
