Given:

The figure of a right angle triangle.

To find:

The value of x and measures of all angles of the triangle.

Solution:

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.

Using angle sum property, we get


(x+60)^\circ+(x+50)^\circ+90^\circ=180^\circ


(2x+200)^\circ=180^\circ


(2x)^\circ=180^\circ-200^\circ


(2x)^\circ=-20^\circ

It can be written as


(2x)=-20

Divide both sides by 2.


x=-10

The value of x is -10.

Now,


m\angle A=x+50


m\angle A=-10+50


m\angle A=40

And,


m\angle B=x+60


m\angle B=-10+60


m\angle B=50

Therefore, the value of x is -10, measure of angle A is 40 degrees and measure of angle B is 50 degrees.
