In a right triangle with acute angle of measure theta, sintheta=1 /2. What is the value of costhetatheta? Draw a diagram as part

Stells [14]

Answer:

0.866

Step-by-step explanation:

By definition

$sin \theta = \frac{Opposite}{Hypotenuse}$

$cos \theta = \frac{Adjacent}{Hypotenuse}$

We know that $sin \theta = 0.5$ . Inverse of sine is arcsin, so, angle $\theta$ is computed as

$\theta=arcsin(0.5)=30$

Therefore, cosine of $\theta$ is

cos (30°) = 0.866

87 = 9/5 c + 32<br> what does c equal??

lawyer [7]

Answer:

c = 30.56 to the nearest hundredth

Step-by-step explanation:

87 = 9/5 c + 32

87 - 32 = 9/5 c

9/5 c = 55

multiply both sides by 5/9:

c = 55*5 / 9

c = 30.56.
