Question

find the missing length for a right triangle with hypotenuse of 18 and leg length of 6. round to the nearest whole number if necessary.

A-17
B-324
C-19
D-36

Thanks :)

Answer 1

formula is. a2 + b2 = c2

the hypotenuse is always C and the leg is always A or B
dosent matter which one

plug in the numbers...

6^2 + B^2 = 18^2
simplify
36 + b^2 = 324
subtract 36 from both sides
36-36 is 0 ... 324 - 36 is 288
b x b is b

so we got b = 288
now find the square root of 288
16.97 rounded its 17

so your answer is 17 :D
