Question

The interior angles of a triangle have measures k°, 27°, and 10°. What is the value of k? Enter your answer in the box.

Answer 1

I just took this quiz.

The answer is 143 because the angles of a triangle always add up to 180. And if you subtract off 27 and 10 from 180, you will get 143.

Answer 2

To find the measure of the third angle you should keep in mind the following:
 The sum of the three interior angles of a triangle is 180 °.
 We have then
 k + 27 + 10 = 180
 Clearing k:
 k = 180-27-10 = 143
 K = 143 °
 Answer:
 the value of k is 143 °
