First find the area of the sector.

For that, use this equation:

area = \frac{x }{360} * \pi r^{2}

where 'x' is the angle and 'r' is the radius

Sub the values in

area = \frac{56}{360} * \pi15^2

Solve:

area = 35\pi

It is easier to keep it in terms of pi until the end

Now, calculate the area of the triangle within the sector

area = 1/2 ab x sinC

where 'a' and 'b' are the radius (side lengths) and C is the angle

thus,

area = 1/2(15 x 15) x sin(56)

area = 93.27 (to 2 d.p)

Now subtract the area of the triangle from the area of the sector

35\pi - 93.27 = 16.6857

This would give you a final answer of 16.69 units^2

A passenger rode the subway 2 blocks west and then 10 south. If all the blocks are the same length what is the value of the slop
Nimfa-mama [501]

Answer:

The slope of the line is 5

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

I have created an illustration which is attached below in order to help you understand the situation. As we are told the passenger rode the subway from point (0 , 0) to point (-2, 0). Then he rode the subway from point (-2, 0) to the final destination of point (-2 , -10). In order to find the value of the slope we need to use the slope formula which is

Slope = \frac{y_{2}-y_{1} }{x_{2}- x_{1} }

Now we just plug in the values of the starting point and final destination in order to find the slope of the line.

Slope = \frac{(-10) - (0)}{(-2)-(0)}

Slope = \frac{-10}{-2}

Slope =5

Finally we can see that the slope of the line is 5

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
