Question

when angle anc is a right angle and angle anb = 2x and angle bnc = 3x then what is angle anb? what is angle bnc?

Answer 1

We know, sum of all the angles in a triangle is equal to 180 degree
So, 90 + 2x + 3x = 180
5x = 180-90
x = 90/5
x = 18

∠ANB = 2x = 2(18) = 36
∠BNC = 3x = 3(18) = 54

Hope this helps!
