This problem wants us to use the law of sines to find the missing parts of the triangle.
00:04
So, um, because i have the two a parts, i'm gonna set up sine 46 over a, which is 27, and we'll look for angle b.
00:16
So we'll say sine b, uh, over 29.
00:21
Okay.
00:22
So if i figure out sine 46 on my calculator, i get 0 .719, and then cross multiply.
00:39
So if i multiply that by 29, i get 20 .86.
00:45
Dividing by 27, i get 0 .773 equals sine b.
00:59
Now to get the angle, i need to use the sine to the minus one button on my calculator.
01:04
And if i type in a couple of digits, so we'll do 772624, 50 .6 for angle b...
