What is the midpoint of the line segment with endpoints (3.5,2.2) and (1.5, -4.8)?

(2.5, -1.3)

Step-by-step explanation:

Add 3.5+1.5 then divide by two and then add 2.2+-4.8 then divide by two. Formula: x1+x2/2 , y1+y2/2

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
