8. Determine the area of a sector with a central angle of 42° in a
circle with radius 3 inches.

Step-by-step explanation:

Since we are given the central angle in degrees, we should use the following formula for sector area.

The angle is 42 degrees and the radius is 3 inches. Therefore,

Solve the exponent.

Multiply all three numbers together.

Let's round to the tenth place. The 9 in the hundredth place tells us to round the 2 up to a 3.

The area of the sector is approximately 3.3 square inches.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
