Hello!

To find the circumference, you multiply the diameter by pi. We will do so below.

2.5\pi≈7.85

a. 7.85 feet

___________________________________________________

To find how many rotations it will take to travel a mile, we will need to divide our mile by our circumference.

5,280/7.85≈672.61

b) 672.61

I hope this helps!

The circumference would be 7.85

And b would be 672.611465 because each time you divide by 7.85 ft

Answer:

A

Step-by-step explanation:

Since cosine is positive and sine is negative that puts θ in Quad IV.

From right triangles we know:

Cos θ = adjacent/hypotenuse = 5/13

sin θ = opposite/hypotenuse = ?/13

To find the opposite side across from θ use the pythagorean theorem.

5² + y² = 13²

25 + y² = 169

y² = 144

y = 12

we are given  that sin is < 0 so sinθ = -12/13

Answer:

Ramiro is correct.

You cannot identify congruent triangles with only angles Angle-Angle-Angle is not one of the rules of congruence. They could have different sizes with the same angles which doesn't makes them congruent. They are similar though. Once you find the missing angles with the equations 62+39+C=180 and 39+79+X=180 the corresponding angles are congruent. So the triangles are not congruent, but are similar.

Please help!!!! I don’t know which one!
Daniel [21]

The correct answer is the first choice. You can determine which angles are congruent by looking at the corresponding angles (angles that are in the same position) on the similar trapezoids). The angles would be congruent even though the shapes are not the same size.
