I have a right-angled triangle. It is labelled A, B and C (for the different sides).
The trianglehas two angles labelled a and b as well as the 90degree angle.
a is 40degrees and is close to A. I was given values for the sides AB, AC and also BC for the previous question I completed. AB was 5, AC was 4 and BC was 3.
For the 1st part of this question (a) AB is 10 (double what is was in the 1st question, I don't know whether it holds any relevance.
The question:
Draw a separate new diagram of triangle ABC and label its dimensions for each of the following:
a) AB=10, AC=x, BC=y. Find x and y
b) AC=10, BC=z, AB=w. Find z and w
c) BC=10, AB=u, AC=v. Find u and v.
sin=O/H
cos=A/H
tan=O/A
O=Opposite
A=Adjacent
H=Hypotenuse.
Please help me! Please tell me how you did it. (write it down in the steps so I can follow so I can learn how to do it). Thankyou.
