Question

8. In a triangle, the three angles are: 60, 11x and 13x degrees. Find the value

of x and plug it in to find the measure of the other two angles. Then classify
the triangle BASED ON ITS ANGLES. *

Answer 1

x=5

Explanation:

60+11x+13x =180° (sum of angles in a triangle )

60+24x=180

24x=180-60

24x=120

x=120/24

x=5

Therefore the angles are 60, 55, 65

Which shows that it is a scaleness triangle and an acute angle
