Find the cosine ratio of angle Θ. Clue: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces. Triangle ABC is shown. AB measures 4. BC measures 5. CA measures 3. The angle formed at point C is marked theta, and angle A is the right angle.

Cosθ = 3/5

Step-by-step explanation:

Given:

In ∆ ABC.

AB measures = 4

BC measures = 5

CA measures = 3

The angle formed at point C is marked theta

angle A is the right angle

Find attached the diagram from the given information.

We are to find the cosine ratio. To do this, we would apply SOHCAHTOA in trigonometry

Sine ratio: Sinθ = opposite /hypotenuse

Cosine ratio: Cosθ = adjacent/hypotenuse

Tangent ratio: Tanθ = opposite/adjacent

From the diagram,

adjacent = AC

hypotenuse = BC

Using the above formula,

Cosθ = adjacent/hypotenuse = AC/BC

Cosθ = 3/5

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
