Answer:
a=9, c=19
Step-by-step explanation:
Aight so basically in 30, 60, 90 triangles there is a formula for the sides
the hypotenuse(the longest side)=2a
The tiny side (the smallest side)=a
and the middle child =
Based on that we see that a is 9
and since c=2a then it's 18
P(pink tile, orange tile)=
7/15 × 6/15 = 42/225
55% because you add 80% and 30% which is 110% and divide that by 2.
