The sum of all the angles in a triangle should always add up to 360° and seeing that this is an isosceles triangle 2 of the angles should be equal.
So there would be 2 30° angles and 360-60=300 so the 3rd angle would be equal to 300° . Hope this helps!

5 3/5 is already a mixed number
3 4/9 is also already a mixed number
43/9 = 36/9 + 7/9 = 4 7/9
32/5 = 30/5 + 2/5 = 6 2/5
Answer:
7a+2a=9a
Step-by-step explanation:
