Answer:
y−4=−7(x−1)
Step-by-step explanation:
The point-slope form of the equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
Your given line has a slope of -7. The parallel line will have the same slope.
So, you want to fill in the above form with m=-7, (h, k) = (1, 4):
y -4 = -7(x -1)
The triangle is an isosceles triangle so that means the base angles must be congruent.
The sum of the interior angles of a triangle add up to 180 degrees.
Subtract 52 degrees from 180 degrees.
180 - 52 = 128
Divide 128 degrees by 2.
128/2 = 64
m∠X = 64°
IQR= 14
Range=18
