Mark and his brother signed up for the Catch Up phone plan. They share the minutes every month equally. How many minutes can Mark use each day without going over his share of minutes?

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

answer: the best approximation for the measure of angle abc applying the trigonometric function cosine in the right triangle abc is

option c) 58.3°

solution:

hypotenuse: ab=20 cm largest side opposite to the right angle (angle of 90°)

angle abc = x =?

adjacent leg to angle abc = bc = 10.5 cm

we have the adjacent side to the angle x and the hypotenuse of the triangle, and we need the angle. the trigonometric function that relates the adjacent side of an angle with the hypotenuse in a right triangle is cosine:

cos x = adjacent leg / hypotenuse

cos x = bc / ab

replacing the given values:

cos x = (10.5 cm) / (20 cm)

cos x =   0.525

solving for x:

x= cos^(-1) (0.525)

x=58.33175674°

rounding to one decimal place:

x=58.3°
