What is the value of x?

A triangle is shown with two sides that each measure 21. The angle between the two sides is 38 degrees. One of the other base angles is labeled x degrees.

Answer 1

Answer: 71°

Step-by-step explanation:

Since the triangle is having two equal sides, it is an isosceles triangle, therefore it will also have equal angles.

Since one of the angle is X, the two angles will be 2X

2X + 38° = 180° ( sum of interior angles in a triangle)

2X = 180° - 38°

2X =142°

To get just one of the angles which the x is representing in the figure, we simple divide bothside by 2

2X/2 = 142/2

X = 71°
