the hyptontuse of a right triangle is 15 one leg is 8 what is the other leg?

Question

a]14
b]15
c]17
d]20

Answer 1

the hypotenuse is 17...you messed up your question....the legs are 8 and 15....and the hypotenuse is 17....

take leg A = 8 and leg B = 15

the hypotenuse C^2 = A^2 + B^2

C^2 = 8^2 + 15^2

C^2 = 289

C = 17

if you have the question as is...there'd be no answer

Answer 2

By Pythagoras Rule:

Hypotenuse^2 = Leg1^2 + Leg2^2

15 x 15 = 8 x 8 + Leg2^2

Leg2^2 = 225 - 64

Leg2^2 = 161 = 12.6885

Answer 3

By Pythagoras x^2 + 8^2 = 15^2
So x^2 = 225-64 = 161.
So x is sqrt(161), which is none of the answers above.

Re your other question, you need to explain what Y is before anyone can help you with the volume.

Answer 4

Let other leg be x
15² = 8² + x²
x² = 15² - 8²
x² = (15 - 8).(15 + 8)
x² = 7 x 23
x² = 161
x = 12.7
None of above answers apply?

Answer 5

Pythagorean theorem

a^2 + b^2 = c^2
15^2 + 8^2 = c^2
c^2 = 289
c = 17

Answer 6

the answer is the square root of 161 (225-64) so it's none of your answers provided

Answer 7

okay .use phytogras's therum A Squared + b Squared=C Squared



| hypotenuse (c)
a |
|
|_________________
b


X Squared +(8) Squared=15 squared


or you can use the sin,cos and tan if you know he angles in the triangle

Answer 8

process of elimination. the hypotenuse MUST be the LONGEST side. so the leg can't be B or C or D.

All that is left is A.
