Find the value of x.
"

Given: A right-angle triangle with angles x and 30.

To find: We have to find the value of x.

Solution: 

We know that in a triangle sum of all the angles is equal to 180^o.

∠PQR + ∠QPR + ∠PRQ = 180^o

30^o + 90^o + x = 180^o

120^o + x = 180^o

x = 180^o - 120^o 

x = 60^o
