What is the length of ef in the right triangle below?

F 24

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

10^2 + EF^2 = 26^2

100 + EF^2 = 676

Subtract 100 from each side

100-100 + EF^2 = 676-100

EF^2 = 576

Take the square root of each side

sqrt(EF^2) = sqrt(576)

EF = 24

F 24

Step-by-step explanation:

You have to use the Pythagorean Theorem

a²+b²=c²

(a and b are the legs of the triangle and c is always the hypotenuse)

a²+10²=26²

a²+100=676; now isolate the a² by subtracting 100 from both sides.

a²=576; now square root each side (gets rid of the squared)

a=24

the diver is 33 feet below the surface.

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
