Answer:
Step-by-step explanation:
y = 4x + 1
Slope of line = 4
Slope of perpendicular to line = -¼
Point-slope equation for line of slope -¼ that passes through (12, -7):
y+7= -¼(x-12)
Answer:
BAC is 78°
Step-by-step explanation:
BCA = 180° - BCD ( angle in a straight line is 180°)
= 180° - 113°
= 67°
BAC = 180° - BCA - ABC (angle in a triangle is 180°)
= 180° - 67° - 35°
= 78°
Here is a graph with the vertex plotted onto it!

Answer:
You use the pythagorean theorem given three angles in number two as it is a 30, 60, 90 triangle . The first one is a 60, 90 and a side and the third is a 60, 90 and a side as well. You should be able to find the equations for this easily enough.
