Find the measure of the angle

Mathematics
1 answer:
Alik [6]3 years ago
6 0

Answer:

75

Step-by-step explanation:

We know that EA is a straight line(180) therefore

ang(ECD) = 180 - 115 = 65

The the sum of angles in a triangle is 180 as well therefore:

ang(DEC) = 180 - ang(EDC) - ang(ECD) = 180 - 40 - 65 = 75

A new car is purchased for 15500 dollars. The value of the car depreciates at 7.5% per year. What will the value of the car be,
mixer [17]

Answer:

\$9,709.17  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

V=P(1-r)^{x}  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

P=\$15,500\\r=7.5\%=0.075\\x=6\ years

substitute

V=\$15,500(1-0.075)^{6}=\$9,709.17

Please please help!! I'm not sure if I have the right answer!!

Answer: The area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Step-by-step explanation:

Let r be the radius of the circle having the center O,

⇒ The area of the circle = \pi r^2  square unit.

And, the central angle AOB = \frac{5\pi}{4}\text{ radian}

=(\frac{5\pi}{4}\times \frac{180}{\pi})^{\circ}  ( since, \pi = 180° )

=(\frac{900}{4})^{\circ}

=225^{\circ}

Hence, the area of sector AOB

=\frac{225^{\circ}}{360^{\circ}}\times \pi r^2

=\frac{5}{8}\times \pi r^2 square unit.

Now,

\frac{\text{Area of sector AOB}}{\text{Area of circle}}=\frac{\frac{5}{8}\times \pi r^2}{\pi r^2}

=\frac{5}{8}

⇒ Area of sector AOB = 5/8 × Area of the circle.

Hence, the area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.
