Point A(3,2) is on a circle whose center is C(−2,3). What is the radius of the circle?
goldfiish [28.3K]

Answer:

The radius of the circle is √26.

Step-by-step explanation:

Since point A is on the circle, the distance between that point and the center of the circle is equal to the radius.

To find the distance between two points, the following equation should be used:

x^{2} =(x_{A}- x_{C}) ^{2} + (y_{A}- y_{C}) ^{2}

Replacing the numeric values:

r^{2} =(3- (-2)) ^{2} + (2-3) ^{2}\\r^{2} =(5) ^{2} + (-1) ^{2}\\r=\sqrt{26}

The radius of the circle is √26.

An angle of a right triangle measures 65 degrees. If the length of the side opposite to the angle is 20 ft, what are the lengths
igomit [66]

Answer:

22.07 ft & 9.32 ft

Step-by-step explanation:

by sines rule :

20/sin 65° = r/sin 90° = y/sin 25°

r = 20×sin 90°/sin 65° = 20/0.9063

= 22.07 ft

y = 20×sin 25°/sin 65° =

20× 0.4226/0.9063

= 9.32 ft

A regular polygon has 10 sides. What is the measure of each interior angle of the polygon?
zysi [14]

Answer:

144 = each interior angle

Step-by-step explanation:

The sum of the interior angles of a regular polygon is

(n – 2)180

If it is regular with n sides, divide by n to find each interior angle

(n – 2)180

------------------- = each interior angle

n

We know that there are 10 sides so n = 10

(10 – 2)180

------------------- = each interior angle

10

(8)180

------------------- = each interior angle

10

144 = each interior angle
