Answer:
? = 47°
Step-by-step explanation:
The angle marked B at the intersection of the secants is half the difference of the arcs they intercept.
∠B = (DE -AC)/2 = (142° -48°)/2 = 47°
The unknown angle is 47°.
It could be 5x, 5 being the digit, x being "a number"
The kinetic energy in the faster case is 4X as much (since KE = (1/2)m*v^2). The brakes must do an amount of work that is equal to the original kinetic energy. The brakes exert the same force in either case, so the distace will be 4X as long for the faster case.
Answer:
1:2
Step-by-step explanation:
The area of ΔFED must be 1/4th of the entire area and so must the area of ΔBCD because B and F are the midpoints. Therefore, the area of ABDF is 1 - 1/4 - 1/4 = 1/2 of ACDE's are so the ratio is 1:2.
