Find the equation of the line passing through the point(-3,5) and parallel to the line with equation
: y=-2x+4 .

perpendicular to the line with equat: -2x+y=0 .

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

i just took the test, the correct answer is .. 31.5 in.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
