What are the measures of the three angles?

Question

An isosceles triangle contains two equal angles. Each of these angles is five degrees larger than twice the small angle. What are the measures of the three angles?

Answer 1

x=# of degrees in the smaller angle

2x+5=# of degrees in each of the equal angles

x+(2x+5)+(2x+5)=180

5x+10=180

5x=180-10

5x=170

x=170/5

x=34º

2x+5=2(34)+5=68+5=73º for each of the equal angles

34º, 73º, and 73º
