Question

Solve Triangle FGH. Round to the nearest degree.

a. measure of Angle H = 67; measure of Angle G = 55; measure of Angle F = 58
b. measure of Angle H = 58; measure of Angle G = 67; measure of Angle F = 55
c. measure of Angle H = 55; measure of Angle G = 58; measure of Angle F = 67
d. measure of Angle H = 58; measure of Angle G = 55; measure of Angle F = 67

Answer 1

I don't have the formula you need for this... do you have it nearby? :)

Answer 2

no..sorry

Answer 3

I think it is b but i'm not sure

Answer 5

It's the cosine and sine rules... but I barely remember them... had to look them up, so it probably makes sense for you to read the examples shown.

Answer 6

It is def not b cuz I got for angle G=55

Answer 7

a?

Answer 8

I would say its D

Answer 9

@JakeV8 what do u think?

Answer 10

sorry, distracted ;) Lemme try to solve it again...

Answer 11

I vote D, and not just cuz @swissgirl said so first.

Answer 12

:) Ok

Answer 13

But like do u know how to use the equation? Like I bet you gotta show ur work

Answer 14

That first link I posted earlier actually walks you through, step by step, how to do a problem like this. Rather than repost it all here, you might read through those steps... you should be able to set your problem up in the same way, one step at a time.
