Draw a right angle triangle out and label the sides using the info given and then find the missing side, then just use trig to find the value of tan

#

Ok Ty will that get me the marks tho

#

there’s like another way to use the trig identities right?!

#

@scenic light

#

Is it just that the triangle is better in this scenario?

scenic light Nov 23, 2024, 5:03 PM

#

no trig identities

#

Just application of trig ratios

#

spiral heath that good?

I don’t think you need to tan^-1 as it’s asking for the value of tan x and not x

#

Just leave it as sqrt 11/5 should be fine

#

ahh ok

#

can u help with B

#

spiral heath can u help with B

Yes

#

Same procedure to find cos x

#

However you aren’t told sin x is acute or obtuse

#

So therefore there are two possible values of cos x

#

Are you familiar with a CAST circle?

#

Something like this
