Answer:
30 tennis balls
Step-by-step explanation:
30 to 50 is equal to 3 to 5. And if there are 30 baseballs for every 50 tennis balls, and there are 80 balls in total, well...
30+50=80
So there are 30 tennis balls
We can see that it is an isosceles triangle so base angles are equal.
x + x + 56 = 180
2x = 180 - 56
2x = 124
x = 124/2
Therefore x = 62.
