The hypotenuse of a right triangle measures 18 cm and one of its legs measures 9 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

about 15.6cm.

Step-by-step explanation:

I got my answer of 15.6cm because I did the Pythagorean theorem.

a^2+b^2=c^2

The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.

Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.

In conclusion, the measure of the other leg is about 15.6cm.

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

good luck on your studies! : )
