Answer 1

please help me.

Answer 2

what could be the formula

Answer 3

pythagoreans discovered a formula for this a long long time ago; its usually notated as:

a^2 + b^2 = c^2

Answer 4

square the legs, add the results, and take the square root of it

Answer 5

could the answer be square 75

Answer 6

i spose it could be any of the options provided ....

Answer 7

what are the measures of the legs?

Answer 8

a is 5 and b is 7 but what could be the c

Answer 9

with the 5 and 7, we will get to the "c"

square each value, what do we get?

Answer 10

49+25=75

Answer 11

good,

then: 25+49 = c^2
75=c^2
sqrt(75) = c

so yes, sqt(75) is correct

Answer 12

can you help me with another question

Answer 13

dunno, how hard is it?

Answer 14

Jamal is a safety inspector for a family gym. Recently, guests have been complaining about the diving board saying that it is leaning towards the water. Jamal needs to know whether this diving board is standing up straight or not. Jamal measures the height of the diving board to be 12 feet. The pool is 15 feet across and he measures the diagonal from the other side of the pool to the top of the diving board to be 19 feet. Is the diving board at a 90 degree angle with the ground? Explain how you know.

Answer 15

if you dont know i understand

Answer 16

use the formula again, does a^2 + b^2 = c^2?

does; 12^2 + 15^2 = 19^2 ?

Answer 17

and this is a very small pool, it prolly shouldnt even have a diving board

Answer 18

144+225=361
369=361

Answer 19

since we have a contradictions; the angle is not 90 degrees with the level of the pool

Answer 20

so what could be the answer

Answer 21

it could be :)

Answer 22

so the answer is that it is not 90 degree angle.

Answer 23

correct

Answer 24

that equation i just did is the reason why is not 90 degree angle
