Write the equation of the line that satisfies the given conditions. Express the final equation in standard form.

tiny-mole [99]

For perpendicular lines m2 = -1/m1, i.e. the product of the two slopes equals -1.
x - 5y = 3
5y = x + 3
y = 1/5 x + 3/5 => slope = 1/5

m2 = -1/(1/5) = -5

Equation of a line containing point (-4, 6) with a slope of -5 is
y - 6 = -5(x - (-4))
y - 6 = -5(x + 4)
y - 6 = -5x - 20
5x + y = -20 + 6
5x + y = -14

Please help me find all the missing angles

Answer:

Look at image I attached below.

Step-by-step explanation:

Important points to memorize when finding missing angles like these:

Two angles directly across from each other, not next to, are equal.
All angles that are on one side of a straight line add up to 180°, because a straight line has an angle measure of 180°.
A full spin-around equals 360°.
All angles in any triangle add up to 180°.

When you know all these important rules, the rest is just a matter of adding and subtracting.
