Answer:

140°

Step-by-step explanation:

The long arc intercepted by angle c is 360° -80° = 280°. The measure of inscribed angle c is half the measure of the arc it intercepts.

c = 280°/2 = 140°

i = 3c

i = c + 14

set both equations equal to each-other, we can

solve for c, we must.

3c = c + 14

subtract c from both sides, we must.

2c = 14

divide both sides by 2, we must.

The center on a target has a diameter of 5 inches. The whole target has a diameter of 25 inches. The center of the target takes

Komok [63]

4%

To find the percentage, first find the area of both circles. The area formula is $\pi r^{2}$ . After finding the area of the center of the target (19.625) and the area of the large target (490.625), set up a percent proportion to determine the percentage that the center takes up:

$\frac{is}{of} = \frac{percent}{100}$

$\frac{19.625}{490.625} = \frac{percent}{100}$

Cross multiplying and dividing by 490.625 will give a total of 4%.
