Question

Find the value of X in each of the given triangles.​

Answer 1

`3x + 2x + x = 180 \\ 6x = 180 \\ \boxed{x = 30}`

Angles are 30°,60° and 90°.

x=30 is the right answer.

Answer 2

<DSR + <SRD + <RDS = 180° (Angle sum property)

2x + x +3x = 180°

6x = 180°

x = 180°/6

x = 30°

So, <SRD = x = 30°

<RDS = 3x = 3(30°) =90°

<DSR = 2x = 2(30°) = 60°

Hope it helps !
