briensmarandache · Answer

in steps one and two your using the law of sines to find the angle measure of A and B. 180 - (A+B) = gives the angle of the missing side, because all angles of a triangle must add up to 180, so that gives you C. because it asks for an equation using the perimeter, we can use the law of sines again. where the ratio of degrees per unit of measure can be expressed as 360/15.1/6. so to find c when given the angle C, you take the inverse of C and multiply it by the ratio of degrees per unit

does that help?

anonymous · Answer

Thanks

briensmarandache · Answer

did it help tho, btw those answer were rounded, not sure how pin point they have to be. its important that you understand how i did. do you understand?

anonymous · Answer

No not really but its ok

briensmarandache · Answer

what part do you not understand? is this a trig class?
