The angles of a triangle measure 30°
Angle Sum Theorem states that the sum of the angles inside a triangle must equal 180°. Based on this theorem, what is the measure of angle x? (1 point)
a +b>c
a+c> b
b+c> a
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Since the angles of the triangle measure 30° each, the sum of all three angles is 30° + 30° + 30° = 90°.
Therefore, to find the measure of angle x, we must subtract the sum of the known angles from 180°:
180° - 90° = 90°
So, angle x measures 90°.
