Question

Could someone help me check this? I don't think I did it right....


So, I'm supposed to be solving for value h. Using Longer Leg= Shorter leg times square root 3, I got 20 square root 3/3. I'm pretty sure that's not right. Diagram's in the comments if you can help!

Answer 1

Or use pythagorean theorem

Answer 2

But that will give answer in decimal...... So i would prefer trigonometric ratios

Answer 3

if you are learning about 30-60-90 "special" triangles, then trig is over kill.

you said
Using Longer Leg= Shorter leg times square root 3, I got 20 square root 3/3

shorter side is 10
times sqrt(3)
means 10*sqrt(3)

Answer 4

So, I used the wrong leg?

Answer 5

It looks like it. The triangle has a hypotenuse (across from the 90 angle), a short leg and a long leg. The legs are the sides that are not the hypotenuse

Answer 6

Ah, I get it now

Answer 7

so you need to understand
Longer Leg= Shorter leg times square root 3
means
longer leg = 10 times sqrt(3)
or simply
longer leg = 10*sqrt(3)

Answer 8

Got it! Thank you!
