will you please help answer angle questions using a shape X. Shape X ........ #2 is in the top space of the x, #3 is in the right space of the x, #4 is in the bottom space of the x, and #1 is in the left space of the x. 1. solve m angle 2=______ and y =_____________ thanks !! angle 1 = ______m angle 3 = 6y degrees then x = _____, m angle 2 = (7x +3)degrees, and m angle 1 =(4x + 12) degrees, m angle 4 = ?? 2. if m angle 3 + m

Explanation / Answer

In the given question, Shape X has been divided into 4 quadrants, starting with #1 on left side and going clockwise from there.

To solve the question, remember angles on a straight line always add up to 180 degrees.

Thus, 1) m<3 + m<4 = 180 degrees

2) m<1 + m<2 = 180 = 4x+12 + 7x+3 = 11x + 15 => 11 x = 180-15 =165 => x = 165/11 = 15

Thus, x = 15 degrees; m<1 = 4x15 + 12 = 72 degrees, m< 2 = 7x15+3 = 108 degrees.

and using m<1 = m<3 = 72 (corresponding angles); similarly, m<2 =m<4 = 108 degrees

6 y =72 => y = 12 degrees

just one correction, < 1 and <3 are vertically opposite angles and not corresponding angles.

to solve for y, you can use either of the following:

1) m<2 + m<3 = 180 and substitute values of <2 and <3 in terms of x and y and also substitute the value of x as obtained earlier. OR

2) m<1 = m<3 and use this to solve for y.
