Find the length of each arc. Round your answer to the nearest tenth

Mathematics
1 answer:
Sauron [17]3 years ago
6 0

Answer:

52 yd

Step-by-step explanation:

The formula for arc length is s = rФ, where r is the radius and Ф is the central angle in radians.

Here the central angle is 300° and the radius is 10 yd.

Convert 300° to radians:  

                                                                   π rad

Multiply 300° by the conversion factor ------------

                                                                    180°

obtaining

(300/180)π = 5.2 rad

Then the arc length is s = rФ = (10 yd)(5.2 rad) = 52 yd

Given Ray BA bisects ∠CBD and the diagram below, what is m∠ABD?
Illusion [34]

The measure of the angle ∠ABD is 64 degrees

<h3>How to determine the measure of the angle?</h3>

From the question, we have the following parameters:

Ray BA bisects ∠CBD

∠CBD = 5x + 18

∠ABC = 3x - 2

Because of the bisection, we have

∠ABC = ∠ABD

∠ABC * 2 = ∠CBD

Substitute the known values in the above equation, so, we have the following representation

(3x - 2) * 2 = 5x + 18

Open the brackets

6x - 4 = 5x + 18

Evaluate the like terms

x = 2

Recall that

∠ABC = ∠ABD

So, we have

∠ABD = 3x - 2

This gives

∠ABD = 3 x 22 - 2

Evaluate

∠ABD = 64

Hence, the angle is 64 degrees

A function is expressed by the formula y = 2x + 7. Find the value of y if x is equal to 1; -20; 43.
rosijanka [135]

Answer:

when x = 1 then y = 9

when x = -20 then y = -33

when x = 43 then y = 93

Step-by-step explanation:

Just replace the given values of x ( which are 1 , -20 , 43 ) in the function
