Question

*If ratio of two angles of a linear pair is 7:5. Find the angles.​

Answer 1

Answer:

LET 1ST ANGLE BE 7X

SECOND ANGLE=5X.

THEREFORE,

7X+5X=180

12X=180

X=15

THEREFORE,

FIRST ANGLE=105(7x)

SECOND ANGLE=75(5x)

Answer 2

Sum of Angles on linear pair =180°

Let angles be x

So, ATQ .

Two angles 7x n 5x

Sum of angles forming linear pair= 180°

7x +5x =180°

12x =180°

x =180° /12

x=15

Angle 1 ( 7x

7×15

105 °

Angle 2( 5x

5×15

75°

Checking

Angle 1 +Angle 2=180° .
