All the right triangles are similar.
x is the short side of the triangle with hypotenuse (2+8)=10.
x is the hypotenuse of the triangle with short side of length 2.
x/2 = 10/x . . . . ratio of hypotenuse to short side is the same for similar triangles
x^2 = 20 . . . . . multiply by 2x
x = √20 ≈ 4.47 . . . . . . . matches selection G
Answer:
23+26+17=66
66÷7=9.42
Step-by-step explanation:
as written in the question add (23+26+17)
then divide it with 7 and you'll get 9.42... i think!!
C. 9
If 9 friends come then they all get 4 water balloons and 9 beads (36/9=4, 81/9=9)
The answer can't be D. 10 as 36/10 and 81/10 do not equal whole numbers and her friends can't have a fractional number of water balloons or beads
