Gelneren [198K]

Answer:

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent to one another

in this problem

∠A and ∠B are vertical angles

∠A=∠B

we have

∠A=

∠B=

equate angle A and angle B

solve for x

therefore

the answer is

the measure of angle A is

A circle has a circumference of 28.2628.2628, point, 26 units. What is the diameter of the circle?

saul85 [17]

Answer:

8.28 units

Step-by-step explanation:

The formula for the circumference of a circle is $C=\pi d$

where

$C$ is the circumference of the circle

$d$ is the diameter of the circle

We know form our problem that the circumference of our circle is 26.28 units, so $C=28.26$ . Let's replace that value in our formula and find $d$ :

$C=\pi d$

$26=\pi d$

Divide both sides of the equation by $\pi$

$\frac{26}{\pi } =\frac{\pi d }{\pi }$

$\frac{26}{\pi } =d$

$d=\frac{26}{\pi }$

$d=8.28$

The diameter of the circle that has a circumference of 28.26 units is 8.28 units.
