What is the value of x? enter your answer in the box. x = ° triangle a b c. the measure of angle b is seventy five degrees, the measure of angle c is fifty degrees and the measure of angle a is x.

Triangles are always 180°, so you can do this:

∠A+∠B+∠C = 180°

And you can plug in the angles that you have.

x + 75° + 50° = 180°

Then you get x by itself to find the measure of angle A.

x = 55°

The measure of angle A =x=.

Step-by-step explanation:

Given a triangle ABC

Measure of angle A=x

Measure of angle B=

Measure of angle C=

We know that angle sum property of triangle

By using this property and substitute the value of given angles

By addition property we get

By subtraction property of equality

Now, we get

Hence, the measure of angle A is x=.
