I dont really need the answer i just want to know how to start this for me its really confusing how to start i see 2 triangles one being a 30-60-90 and the other a 45-45-90 and it gives me one lengths.

Question is: Find the lengths of sides a, b and d if c = 3

a breakdown of how to solve this from beginning to end without getting the answer would be very helpful

Since they are all right angled triangle, you can use sine cosine and tangent to figure out all the unknowns

frozen bone sine cosine and tangent maybe help you

looking at this doesnt help me at all

See,
Sin 45= 1/√2=d=3
Thus, d=3/√2cm

#

Similarly sin60=√3/2
Thus, a=2√3cm

#

And, tan60=√3
Thus, b=√3cm
