To write: The steps needed to solve a triangle if
Answer to Problem 3CFU
Three steps
Explanation of Solution
Given information:
Calculation:
Angle A is obtuse so the only way there can be a triangle is if a > b which it is.
So what we need to solve is to find side c , angle B and angle C.
The problem only asks to describe the steps not to solve it.
Step one:
Set up the law of sines proportion for angles A and B. the only unknown is angle B so you can solve for it.
Step two:
Subtract angles A and B from 180 degrees to get angle C.
Step three:
Set up the law of sines proportion for angles A and C. the only unknown is side c so you can solve for it.
The triangle is now solved.
