Add them together and equal them to 90 degree. 2x - 12 = 90, 2x = 112, x = 56
Answer:
5 inches is 12.7 centimeters
You want to divide 48 by 1 2/5 which is 240/7
I’m having that same problem

Equation of straight line in slope form = 》( y-y1) = m (x - x1)
Thus here solving ....
y +3 = -3 (x-4)
=》 y+3= -3x +12
=》 y = -3x +9
option c.) y = -3x +9
