Question

An angle in an isosceles triangle measures 30°. What could the measures of the other two angles be? Consider all options.

Answer 1

180-30= 150DEG SO THE OTHER TWO HAVE TO TOTAL 150DEG, BY USING RULES OF AN ISOSCELES TRIANGLE. ALSO THAT SUM OF INTERIOR ANGLES OF A TRIANGLE EQUAL 180DEG, AND IF ISOSCELES, THEN TWO SIDE LENGTHS OF TRIANGLE ARE THE SAME, AND TWO ANGLES HAVE THE SAME MEASURE. SO OPTIONS ARE;

75+75+30=180 OR 

30+30+120=180

HOPE THIS HELPS! THANK YOU!!!!

Answer 2

30° and 120°

75° and 75°

These are the answers I did an assignment on them hope it helps if it does make sure to leave a like and a five-star rating.
