Question

Find the value of x in the triangle shown below 3.5 4 3.5 x• 55•

Answer 1

Answer:

Step-by-step explanation:

Since this is not a right triangle, we will use the Law of Sines. For us that looks like this:

$\frac{sin55}{3.5} =\frac{sinx}{4}$ and cross multiply to get

4sin55 = 3.5sinx and solve for sinx:

$sinx=\frac{4sin55}{3.5}$ so

sinx = .9361737 Use the 2nd button on your calculator and the sin button to find that the angle

x = 69.4°. Not sure how you need it rounded. It's actually 69.4186°
