Kamal is 17 years older then gina. gina is 3 years younger then reachelle. if the sum of there ages is 77 how old is gina?

Gina's age is 18

Step-by-step explanation:

Set up an equation

Kamal = g + 17

g being Gina's age

Gina = r - 3

r being Rachelle's age

Rachelle = x

Now change every letter to x and write the equation

(x + 17) + (x - 3) + x = 77

3x + 14 = 77

     - 14  - 14

3x = 63

Then plug in x for Gina's age

x - 3 = (21) - 3 = 18

300pi

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
