Question

angle L = 3x angle M =90 angle N = 2x

Answer 1

Answer:

x = 18

Step-by-step explanation:

3x+2x+90 = 180 ( sum of angles of ∆ is 180 )

5x + 90 = 180

Answer 2

Step-by-step explanation:

So as we know angles of a triangle are supplementey that means 180 degree .

:. angle L +angle M +angle N = 180 degree

3x+ 90 + 2x= 180 => 90+5x= 180 => 180-90=5x+> 90 =5x=> x=90/5

:. x= 18

THEREFORE X IS EQUAL TO 18
