Answer:21
Step-by-step explanation:
It's a 1-7 proposition for every ft on the smaller triangle it is 7ft on the big one
This is called the commutative property (ies).
Search the commutative property of Multiplication, addition, etc...
Its 264.
This is because its looking for the lateral surface area. And the formula for that is S=Ph.
So that means you add up the perimeter and multiply the height.

P(x) = 0.55
P(x ∪ y) = 0.70 →→ P(x) +P(y) = 0.70 →→ 0.55 + P(y) =0.70→→P(y) = 0.15
If P(NOT y) = 1- 0.15 = 0.85
