Question

A movie screen is 15 meters by 8 meters. What is the length of the diagonal of the movie screen? *

120 m2
26.5 m
17 m
70 m

Answer 1

17,

Diagonal= sqrt w^2+l^2

Answer 2

Answer:
17 m

Explanation:
Use the pythagorean theorem to find the length of the hypotenuse:
Pythagorean theorem:

`a^(2) + b^(2) = c^(2)`
a = 15 and b = 8

`15^(2) + 8^(2) = c^(2)`
Solve for c:

`15^(2) + 8^(2) = c^(2)`
225 + 65 =
`c^(2)`
289 =
`c^(2)`

`√(289)` = c
17 = c
