# Thread: Solve the following right triangle?

1. ## Solve the following right triangle?

ABC is a right triangle where the right angle is at vertexC.the acute angles at vertices A and B are donoted by alpha and beta respectively.
Solve the following right triangle
a) alpha = 60°,c=2.7
Please dram the diagram showing me where are ABC located and where are alpha and beta angles located?

here.

of course you know a is opposite angle A, b is opposite angle B and c is opposite angle C

3. Here is what your triangle looks like according to your description.

Angle B=60 deg and angle A=30 deg.

Use sine and cosie to find the side lengths a and b.

$\displaystyle a=2.7sin(30)$

$\displaystyle b=2.7cos(30)$

or

$\displaystyle a=2.7cos(60)$

$\displaystyle b=2.7sin(60)$
