What’s the measure of the angle theta?
11111nata11111 [884]

Answer:

∅ = 50°

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

You need to use Law of Sines

\frac{a}{sinA} =\frac{b}{sinB} = \frac{c}{sinC}

Here you will be doing \frac{a}{sinA} =\frac{c}{sinC}

a and c are the lengths, while A and C are the angles

\frac{3.46}{sinA} = \frac{2.54}{sin43} you want to get the denominators out from underneath so multiply both sides by sinA and sin43

3.46sin43 = 2.54sinA

Now you want to get sinA alone so divide both sides by 2.54

\frac{3.46sin43}{2.54} = sinA now get A alone

sin^{-1} (\frac{3.46sin43}{2.54}) = A put that into the calculator

49.61741033 = A
