Answer:
y = -5
Step-by-step explanation:
A line perpendicular to x = 5 is a horizontal line. Here this horiz. line passes through y = -5. This last result is the desired equation.
Answer:
True

Answer:
b = 55 degrees
Step-by-step explanation:
The angles 30, a, b and 45 must sum up to 180 degrees
Subtracting (30 + 45) from both sides leaves us with a + b = 105 degrees.
But b = a + 5. Substituting a + 5 in the equation above yields
a + a + 5 = 105 degrees, so that
2a = 100 degrees, and a = 50 degrees. Then b = a + 5, or b = 55 degrees.
