Question

If m∠1= (7x –19)°, and m∠2 = (x + 5)°, find m∠2.

Answer 1

Given :

∠m1 = ( 7x - 19 )° .

∠m2 = ( x + 5 )° .

To Find :

The value of x .

Solution :

Since , relation between angle ∠m1 and ∠m2 is not given .

Let , us assume that sum of ∠m1 and ∠m2 is 180° .

So ,

Angle ∠m2 = (24.25 + 5 )° = 29.25° .

Therefore , ∠m2 = 29.25° .

Hence , this is the required solution .

Answer 2

Given :

∠m1 = ( 7x - 19 )° .

∠m2 = ( x + 5 )° .

To Find :

The value of x .

Solution :

Since , relation between angle ∠m1 and ∠m2 is not given .

Let , us assume that sum of ∠m1 and ∠m2 is 180° .

So ,

`(7x-19)+(x+5)=180^(\circ)\\\\8x-14=180\\\\8x=194\\\\x=24.25^(o)`

Angle ∠m2 = (24.25 + 5 )° = 29.25° .

Therefore , ∠m2 = 29.25° .

Hence , this is the required solution .
