Question

Find the value of x and y.

Answer 1

one angle = 30, 2nd angle = 90 deg therefore third angle = 60
Hence given is a 30, 60 90 degree triangle

Answer 2

May i solve it using Trigonometry?

Answer 3

I think I already found an answer, but I'm awful at proofs and my grade point average in geometry is starting to drop, so I want to be absolutely sure it's right

Answer 4

sure, whatever works for you

Answer 5

:)

Answer 6

Ok, wait...

Answer 7

\[\huge \sin 30^0 = \frac{x}{20} \]
\[\huge \rightarrow \frac{1}{2} = \frac{x}{20} \rightarrow x= 10\]

Answer 8

!!!!
Confusion, confusion

Answer 9

Exterminate confusing math! Exterminate!

Answer 10

But I got 10 for x, too, so I guess that's good

Answer 11

They also say to leave all answers reduced radicals, just fyi

Answer 12

\[\huge \cos 30^0 = \frac{y}{20}\]
\[\huge \frac{\sqrt 3}{2} = \frac{y}{20}\]
\[\huge 2y = 20 \times \sqrt3 \]
\[\huge y = 10 \sqrt3 \]

Answer 13

I didn't do it with the first one, because it divided evenly, but I did leave y as a reduced radical

Answer 14

YES!
Thnx, that's exactly what I got
