Question

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. If a=18 centimeters and b=80 centimeters, what is c? If necessary, round to the nearest tenth.

y-intercept

Answer 1

You’d use pythagoras theorem for this answer. Use the formula h²= a²+b², where h is the hypotenuse. Here’s the step by step:

h²= a²+b²
x²= 18 ²+80 ²
x ²= 324+6400
x ²= 6724

then find the square root of 6724 (I can’t find the symbol on my phone lol) which is 82cm. So that means that h=82cm/c=82cm.

Hope that helped!!
