Now, simplify. Add like terms.

9x-1-2=p

9x-3=p

9x-3

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

Nadusha1986 [10]

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.

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