how to work out the percentage of a triangle that is shaded by a circle??

(circle is at a tangent to all 3 sided if that helps)

thanks

sorry just tring to work out equation to get percentage not the ans

How do you factor this expression completely? x^2-49

How do you express x^2-49?

(x+7)(x-7)

X(times)X = X^2
(positive 7) (times) (negative 7)= -49

X^2-49
is (x+7)(x-7).

To work out the percentage of a triangle that is shaded by a circle, you will need to determine the ratio of the shaded area to the total area of the triangle, and then convert it into a percentage.

Here are the steps to follow:

1. Find the area of the triangle:
- Measure the lengths of the base and height of the triangle.
- Multiply the base length by the height length.
- Divide the result by 2 to get the area of the triangle.

2. Find the area of the circle:
- Measure the radius of the circle. (In this case, it would be the distance from the center of the circle to any one of its tangent points with the triangle.)
- Square the radius (multiply it by itself, r^2).
- Multiply the squared radius by π (pi) to get the area of the circle.

3. Find the ratio of the shaded area to the triangle area:
- Subtract the area of the circle from the area of the triangle to get the shaded area.
- Divide the shaded area by the area of the triangle.

4. Convert the ratio into a percentage:
- Multiply the ratio by 100 to obtain the percentage.

Remember, the shaded area is the region between the circle and the triangle, where the circle is tangent to all three sides of the triangle.
