Marika is training for a track race. she starts by sprinting 100 yards. she
gradually increases her distance, adding 4 yards a day for 21 days.
which explicit formula models this situation?
o a. an = 21 + (n - 1)4
o b. 2n = 100 + (n − 1)4
o c. an = 100 + (n − 1)21
o d. an = 4 + (n − 1)100

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

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
