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.

Answer:
y= -3x +10
the y-intercept is at 10 and then go 3 down one to the right
Step-by-step explanation:
Answer:
B y+8 = 2(x-4)
Step-by-step explanation:
perpendicular slope is a negative reciprocal of the x
which is 2x
then use the formula
y-y1 = m(x-x1)
y + 8 = 2(x-4)
