Can someone help me with all these questions please!! it’s very annoying when people just put something for points ... if u don’t know, don’t answer !

Step-by-step explanation:

15) tanA = 6.8/3.0

16) tanR = 9/24

17) tanB = 16/17

18) BC = 10tan40

19) PQ = 38/tan75

20 BC seems to be missing some of its length number I will call it 14

redo if that is incorrect.

∠A = arctan(14 / 14.5)

∠C = arctan(14.5 / 14)

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
