Answer:
Angle ADC = 58 degrees
Step-by-step explanation:
Since it is a right angle...
(-6x + 2) + (-4x + 38) = 90
-10x + 40 = 90
-10x = 50
x = -5 ---- > -4(-5) + 38 ---> 20+38 ---> 58
Answer:
119cm

Answer:
110/170 = 0.6471 = 64.7% or 65%
Step-by-step explanation:
reading | television
Television | 70 | 20 | 90 total for TV
___________________________________________________
Reading | 40 | 40 | 80 total for reading
___________________________________________________
Total students | 110 | 60 | 170 total students
Students who like BOTH are 70 + 40 = 110 percentage = part/whole = 110/170
Students who ONLY like television = 20
Students who ONLY like reading = 40
