The quadratic formula is above.

You want each equation in standard form: ax^2 + bx + c = 0
I begin each problem by defining variables.
For instance 3. Is in standard form. X^2 -2x - 3 = 0. a = 1, b = -2, c = -3

Now use quadratic formula: x = [- b + or - sqrt(b^2 - 4ac)]\2a

Simple,

1.) A vertical angle, is an angle directly across another angle. Thus, <2 and <5 are vertical angles.

2.)This is another pair of vertical angles, thus, m<4 is 53.

3.)Since m<1 is 50

You have the m<4 which is 50. You already have m<3 which is the right angle, 90. 

Thus, 90+50=140

You know a line is supposed to be 180 degrees. So take,

180-140=40

Thus, the m<5 is 40.
