Question

solve the triangle. B = 36°, a = 41, c = 17

Answer 1

well you can draw a diagram



now it depends on what you need to find...? and angle A or C or side b

Answer 2

can you walk me through this please

Answer 3

im suffering

Answer 4

ok... so lets start by finding b... you need to rule of cosines

\[b^2 = 17^2 + 41^2 - 2 \times 17 \times 41 \times \cos(36)\]

Answer 5

okay i'm tryiing to work it out hold on

Answer 6

i got 289+1681x1394 cos 36

Answer 7

Answer 8

b=465?

Answer 9

i mean 21.5

Answer 10

@campbell_st

Answer 11

well I got 29.02

I've checked it and think I'm right...

so next to find an angle...

say angle A

use the law of sines

\[\frac{\sin(A)}{41} = \frac{\sin(36)}{29.02}\]

now solve for A
