Angle B measures 60°. What is the measure of the angle that is complementary to angle B?

vodomira [7]

Complementary angles add up to 90.
Say the complementary angle is A.
Angle A + Angle B = 90
Angle A + 60 = 90
Angle A = 30 degrees

Hope this helps :)

Answer:

The image below will explain the question

To figure out the length of portion BC, we will use the trigonometric ratio below

$\begin{gathered} \sin\theta=\frac{opposite}{hypotenus} \\ oppsite=BC \\ hypotenus=8in \\ \theta=35 \end{gathered}$

By substituting the values, we will have

$\begin{gathered} \sin(\theta)=\frac{oppos\imaginaryI te}{hypotenus} \\ \sin35=\frac{BC}{8} \\ cross\text{ multiply, we will have} \\ BC=8\sin35 \end{gathered}$

Hence,

The final answer is
