Question

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided 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. Thank You Alot

Answer 1

We know that the sum of a triangle's angles equals to 180 degrees.

We also know using the information given that this triangle is an isosceles triangle making two of it's angles equal.

We also know that the angle between the two sides is 38 degrees.

Now all we need to do is subtract 38 from 180 then divide by 2 which will give us the angle measurement of x as both the angles are considered as x.

(180-38)/2

=142/2

= 71.

therefore the value of x is 71 degrees.
