$465,262 / 240 (12 x 20) = 1983.5 = $1,939
Answer:
The measure of the central angle whose radii define the arc is
Step-by-step explanation:
Radius of circle = 10 cm
Length of arc =
We need to find Theta
The formula used will be:
S= length of arc, r = radius and = angle
Putting values and finding \theta
So, the measure of the central angle whose radii define the arc is
The base of given triangle is 8 cm.
Further explanation:
The area of triangle is calculated by using two methods
- Hero's formula
- Base and Height
Hero's formula requires all three sides of triangle while we can use only base and height in second formula.
Given
As the area of triangle and height are given, then
The base of given triangle is 8 cm.
Keywords: Area of triangle, base, height

Answer:
190
Step-by-step explanation:
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
