Question

Solve the Right.Triangle Round decimals to the nearest tenth.

Answer 1

Hint: You need trigonometry, Pythagorean's theorem and angle sum of triangle for these questions.

Answer 2

For trigonometry would that be like trig ratios(quite don't understand that)

Answer 3

Yes, precisely that. sin(x) = opp/hyp, cos(x) = adj/hyp, tan(x) = opp/adj.

Answer 4

For the first problem should I just find the answer by using sin,cos or tan

Answer 5

@jdoe0001 hey you were right and can you check the diagram because I finally fixed it so... then I realized you were right in the first place

Answer 6

For angles, you use sin, cosine and tangent (and their inverse functions). You will need a calculator for this.

Answer 7

So for the first one you can do Pythagorean Theorem?? then sin,cos or tangent then find the angle sum of a triangle

Answer 8

Not sure what you're talking about. For length of lines you use Pythagorean's Theorem. For angles, you use the trig functions (and their inverses).
