Question

What is the value of x? A. 142 B. 152 C. 76 D. 71

Answer 1

Answer:

x has a value of 71, making D the correct answer.

Step-by-step explanation:

Because this is an isosceles triangle, we know that the bottom two angles are equal.  We also know that the sum of the angles inside a triangle will always come to 180°.  With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.

$x = (180 - 38) / 2\\= 142 / 2\\= 71$

So the correct answer is D, 71 degrees.
