Find The Length Of The Hypotenuse Of A Right Triangle : Pythagorean Theorem : Example Question #1
Trig_id
If o=10ft and a=17ft, how long is side h?
Possible Answers:
Not enough information to solve
17.9ft
19.7ft
18ft
19.3ft
Correct answer:
19.7ft
Explanation:
This problem is solved using the Pythagorean theorem (a2+b2=c2). In this formula a and b are the legs of the right triangle while c is the hypotenuse.
Using the labels of our triangle we have:
o2+a2=h2
\dpi{100} h^{2}=(10ft)^{2} +(17ft)^{2}
h2=100ft2+289ft2
h=389ft2−−−−−√
→19.7ft
