Answer: Choice B

15 + 5*sqrt(3)

=======================================================

How to get this answer:

Let A, B, C be the sides of the triangle such that  A < B < C.

A is the short leg, B is the long leg, C is the hypotenuse

For any 30-60-90 triangle, the hypotenuse is twice as long as the short leg, so

C = 2*A

C = 2*5

C = 10

For any 30-60-90 triangle, the long leg is exactly equal to sqrt(3) times the short leg

B = A*sqrt(3)

B = 5*sqrt(3)

Now add up the three sides

A+B+C = 5+5*sqrt(3)+10

A+B+C = 15+5*sqrt(3)

can someone answer these 2 questions asap and thank you its also double the points because it 2 questions ;)
Juli2301 [7.4K]

9:

r\leq15.5 (not the one with the line under it i just couldnt find the one that didnt have the line under it)

for the graph, put 16 on the right side and label the lines right to left 16 15.5 14 14.5 etc. Put an open circle on the 15.5 line. then make an arrow pointing to the left.

10:

80\leqp+64

This is because she needs 80 points OR MORE and (p represents the points) she already has 64. She needs 80 to be less than or equal to the amount of points earned.

The solution is 16\leqp because 80-64=16 and p is needs to be greater than or equal to 16
