Triangle ABC has measures a equals 2 b equals 2 and angle a equals 30 degrees what is the measure of angle B
Stella [2.4K]
<h2>Hello!</h2>

The answer is: Angle B is 30°

<h2>Why?</h2>

Since we know that both sides, a and b are equal to 2, and angle A is equal to 30°, we can conclude that angle B is also equal to 30°. Also, we can know that the other angle (C) will be equal to 120° since the sum of all the angles in a triangle will be always equal to 180°.

Have a nice day!
