Answer: C. 84

Step-by-step explanation:

In triangles ABD y BCD:

- AD=CD

- Angle BAD = angle BCD

- BD common side

THEN the triangles are equal because they have two sides and the angle opposite the longest side respectively equal.

CBD = ABD = 42 because the triangles ABD y BCD are equal

Pani-rosa [81]

Answer:

16 ft²

Step-by-step explanation:

Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.

Area of remaining body = area of full body - area of removed body.

Area = πd²/4

Area of remaining body = (π * 5²)/4 - (π * 2²)/4

Area of remaining body = 19.64 - 3.142

Area of remaining body = 16.49 ft²

Therefore, the remaining area is then calculated into 16 ft²

Nine years ago, Kimo was twice as old as Jennifer was then. In four years, Jennifer will be the same age that Kimo is now? How o
Georgia [21]

Answer:Kimo is 17 years old and Jennifer is 13 years old.

Step-by-step explanation:

Let x represent Kimo's current age.

Let y represent Jennifer's current age.

Nine years ago, Kimo was twice as old as Jennifer was then. It means that

x - 9 = 2(y - 9)

x - 9 = 2y - 18

x = 2y - 18 + 9 = 2y - 9

In four years, Jennifer will be the same age that Kimo is now. It means that

x = y + 4 - - - - - - - - - 1

Substituting x = 2y - 9 into equation 1, it becomes

2y - 9 = y + 4

2y - y = 4 + 9

y = 13

x = 2y - 9 = 2 × 13 - 9

x = 17
