Hello can u help me

Answer 1

ummm yes, do u know the sine rule

Answer 2

@aprilann143 ...?

Answer 3

so what would i do first?

Answer 4

so the sine rule states
\[\huge \frac a{\sin A} = \frac b{\sin B}\]
si in your triangle, what do you thing a, A, b and B will be?

Answer 5

22

Answer 6

which?
a?
A?
b? or
B?

Answer 7

im not sure im confused?

Answer 8

\[\huge \frac a{\sin A} = \frac b{\sin B}\]
so did u se the first picture i posted?
so sub those values into the equation above, and solve for x

Answer 9

a=53

Answer 10

yep
a = 54
A = 77
b = x
B = 22

Answer 11

oh ok how u get 54?

Answer 12

But it says 53 not 54

Answer 13

sorry, yep, ur right, my bad (typo)
a = 53

Answer 14

ok

Answer 15

so \[\huge \frac a{\sin A} = \frac b{\sin B}\]
\[\huge \frac {53}{\sin A} = \frac x{\sin B}\]
\[\huge \frac {53}{\sin 77} = \frac x{\sin 22}\]

can u solve from here ?

Answer 16

no what do i do

Answer 17

so on ur calculator, what is sin 77 degrees?

Answer 18

sin 77=09

Answer 19

to 5 digits though?

Answer 20

wait what?

Answer 21

sin 77 doesnt = 9
what's sin 77 (round the answer to 5 decimal places)
