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

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)\$
