In a right triangle, one angle is equal to 90 degrees while the sum of the other two angles are also 90 degrees. In this case, x is a right angle, so it equals 90 degrees. We know that one of the other angles is 47 while the second is y. So, y+47=90. To find y, we subtract 47 from 90, which is 43 degrees. y=43 degrees.

<span>90+47=137 X is a right angle so it is going to equal 90 that is where the 90 came from.

180-137=43 to find y we have to subtract 180 (the sum of all triangles) by the sum of x and 47. Which ends up being 43.
X= 90
Y= 43</span>

Line AB passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to
amid [387]

parallel means "same slope (m)"

m = \frac{y2 - y1}{x2 - x1} = \frac{0 - 5}{-3 - (-6)} = \frac{-5}{-3 + 6} = \frac{-5}{3}

Now, input the point (0, 0) and the slope (\frac{-5}{3}) into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 0 = \frac{-5}{3}(x - 0)

    y = \frac{-5}{3}x

 3y = -5x    <em>multiplied both sides by 3</em>

 0   = -5x - 3y  <em>subtracted 3y from both sides</em>

Answer: C
