Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles given and equate to 180

4x - 13 + 15 + x + 18 = 180 ( simplify left side )

5x + 20 = 180 ( subtract 20 from both sides )

5x = 160 ( divide both sides by 5 )

x = 32

∠A = 4x - 13 = (4 × 32) - 13 = 128 - 13 = 115°

∠C = x + 18 = 32 + 18 = 50°

As a check : 115° + 15° + 50° = 180° ← correct

What is the equation of the circle with center (0, 0) that passes through the point (–4, –6)?
Vadim26 [7]

If the center is in point P(a,b) and has a radius r then circle equation is:

(x-a)²+(y-b)²=r².

In your task we've got P(0,0) so the circle equation is x²+y²=r².

We have to find r. Radius start at (0,0) and end at (-4,-6) therefore

r=√((-4)²+(-6)²) and

r²=(-4)²+(-6)²=16+36=52.

So answer is x²+y²=52.

PLEASE HELP ASAP I WILL LOVE YOU 4EVR
Anni [7]

Answer:

96

Step-by-step explanation:

IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."

Now the circumference of a circle is an arc length.  And the ratio of the circumference to the diameter is the basis of radian measure.  That ratio is the definition of π.

π   =   C

D .

Since D = 2r, then

π = C

2r

or,

C

r  =   2π .

arc lengthThat ratio -- 2π -- of the circumference of a circle to the radius, is called the radian measure of 1 revolution, which are four right angles at the center.  The circumference subtends those four right angles.

arc length

Radian measure of θ  =   s

r

Thus the radian measure is based on ratios -- numbers -- that are actually found in the circle.  The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For, the ratio of s to r does determine a unique central angle θ.

A sphere has a diameter of 24 units. What is its volume in cubic units?
34kurt
V = (4/3)π.R³

Diameter - 24 units so Radius = 24/2 = 12 Inits

V= (4π/3).12³ =(4π/3). 1728
V=1728  x 4/3 x π = 2,304.π units³
