By Angle sum property,
Sum of all angles of a triangle equal to 180°.

As per the property,
A+B+C = 180°
4x-13 + 15 + x+18 = 180
5x+20 = 180
5x = 160
x = 32

Measure of Angle A =>
4x-13 = 4*32-13 = 128-13 = 115°

Measure of Angle C =>
x+18 = 32+18 = 50°

!! Hope It Helps !!

Henry constructed circle A with a radius of 4 units. He then created a sector as shown in the figure below. Which of the followi
Ksivusya [100]

Answer: option D is the correct answer

Step-by-step explanation:

The shaded portion of the circle is the smaller sector whose radius is the same as the radius of the circle which is given as 4 units. The sector is always bounded by two radii with a common point which is the center of the circle and forming an angle at that point. The given sector forms an angle of 45 degrees.

Area of a sector is expressed as

#/360 × π × r^2 and # is in degrees

Therefore, area of the shaded portion or sector = 45/360 × π × 4^2

= 45/360 × 16π

= 45/360 (16π)

The path of a ball kicked from the ground can be modeled by the equation y=−1/5(x−5)(x−20), where x and y are measured in feet.
Helen [10]

Answer:

Step-by-step explanation:

This is already factored for the zeros of the quadratic.  If x - 5 = 0 and x - 20 = 0 then x = 5 and 20.  The ball was kicked 5 feet out and landed at 20 feet down the field.  The difference is 15 feet.  That's how far the ball traveled from its initial position on the ground to its landing place.

So 15 feet from where it was kicked.
