Algebra Help. Please?

Answer 1

1. In the given right triangle, find the missing length
28 m
26 m
25 m
27 m

Answer 2

use pythagoras theorem

Answer 3

How do I use that? I just started a new math class and I need to fill out a 'pre-review' sheet of what they are doing...

Answer 4

Hmm. Okayy. I will figure that one out.

Answer 5

Two flag poles in front of the courthouse are 12 ft tall. The distance from the top of one pole to the base of the other as shown in the diagram is 20 ft. What is the distance between the two flag poles?

16 ft
23 ft
18 ft
15 ft

Answer 6

for the one befor:
\[10^{2}+24^{2}=c ^{2}\]

Answer 7

Okay thanks!

Answer 8

c=26

Answer 9

Which of the following could NOT be the lengths of the sides of a right triangle?
9 ft, 12 ft, 15 ft
5 in., 10 in., 15 in.
4 cm, 7.5 cm, 8.5 cm
1.5 m, 2 m, 2.5 m

Answer 10

You have hypotenuse and one side. To find the other,
x^2 = 20^2 - 12^2
x = √256 = 16

Answer 11

Oh, I remember doing something like that before...

Answer 12

To prove that it is right triangle,
Find the square of the length of the longest side, yielding a value say x
Then find the square of the sum of the other two sides, yielding a value say y.
If x = y, then it is right triangle

Answer 13

I mean sum of the square of the other two sides

Answer 14

Okay great!

Answer 15

Answer 16

a^2+b^2=c^2
This is pythagoras theorem
