find the length of C if the measure of angle A=62 degrees, the measure of angle B=39 degrees and b=15
|dw:1375852258872:dw|
ok so b=15 and a=21.04
@trevor214 how did you get that? -.-
somebody said do 62(sin) 39(sin) and then divide
ummmm.... yes. \[a = 21.0452 \]
yes here the q is about finding the length of side c
|dw:1375852595395:dw|
hmm seems like we need to find C (aka angle C)
ganeshi8 yes
It's length of C, so I'm assuming it's the side, @some_someone Besides, finding angle C is almost trivial XD
@trevor214 Traditionally (if not as a standard), the sides of a triangle are represented by lowercase letters and their corresponding opposite angles are represented by their respective uppercase letters. So if you need a side-length, please use lowercase letters to represent them :)
Unless the notation is wrong? Because CAPITAL LETTERS are angles. lower case letter are side lengths.
yeah c is a side length
Yes, thank you TJ :)
In any case, both are technically unknown anyway, so @trevor214 What's the measure of C, or this angle?|dw:1375852721359:dw|
You need that ^ angle to compute for the length of side c, so, what's the measure of that angle? Remember that the sum of the three interior angles of a triangle is ALWAYS 180 degrees...
