On a circle of radius 7 feet, what wlangke would substend an arc of length 7 feet?

1 answer:

6 0

Arc length = radius * central angle (in radians)
central angle = arc length / radius
central angle = 7 / 7
central angle = 1 radian
central angle = 57.296 degrees

(2.07) The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F: C = 5

Vlad [161]

C = 5/9(F - 32)....multiply both sides by 9/5
9/5C = F - 32...add 32 to both sides
9/5C + 32 = F

If side A is twice as long as B and C is 25 using the Pythagorean Theorem,What are the lengths of side A and B? Round to the nea

777dan777 [17]

Answer:

The lengths of side A is 22.4 and B is 11.9.

Step-by-step explanation:

Given:

If side A is twice as long as B and C is 25 using the Pythagorean Theorem.

Now, to find the lengths of side A and B.

Let the side B be $x.$

So, the side A be $2x.$

Side C = 25.

Now, to solve by using Pythagorean Theorem:

A² + B² = C²

$(2x)^2+(x)^2=(25)^2$

$4x^2+x^2=625$

$5x^2=625$

Dividing both sides by 5 we get:

$x^2=125$

Using square root on both sides we get:

$x=11.18.$

B rounding to the nearest tenth = 11.9.

Now, to get A by substituting the value of $x$ :

$2x\\=2\times 11.18\\=22.36.$

A rounding to the nearest tenth = 22.4.

Therefore, the lengths of side A is 22.4 and B is 11.9.
