Check the picture below.
notice that, the diagonal is really just a traverse line cutting through the parallel segments of AB and DC, and since those angles are alternate interior ones, that means 5y - 1 = 7y - 15, and 6x - 6 = 4x + 2, therefore
615,624,633,642,651,165,264,363,462,561,156,246,336,426,
516,426,246,651,642,624,615,561,462,264,165.
I think more than this no possibilities are available.
Answer:
3. Parallel lines have the same slope but different y-intercepts, so they never intercept each other.
Step-by-step explanation:
Basically what you need to do is add up the expressions, 7x and 3x and make it equal to 90 degrees. Then solve for x. Substitute the value of x for each expression to determine the values of each angle.
7x + 3x = 90
10x = 90
X = 90/10
X = 9.
Angle 1 = 7(9) = 63 degrees
Angle 2 = 3(9) = 27 degrees.
Check
63 + 27 = 90
90 = 90.
