Question

Please help me

Solve the right triangle. Round to the nearest tenth, if necessary.

Answer 1

c = 32.1

b = 34.4

`m\angle{B}=` 47 degrees

Explanation:

Using sine = opp/hyp. to find side c:

`sin(43)=(c)/(47)=32.05392...`

Using cosine = adj/hyp. to find side b:

`cos(43)=(b)/(47)=34.37362...`

Finding angle B:

It's a right triangle and you're given one of the acute angles, which means you can find the missing third angle. All triangles interior angles add to equal 180 degrees.

180 - (43 + 90) = 47 degrees
