In the figure show that angle a+angle b+angle c+angle d =4 right angle ​

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =

What is the missing reason in the proof? segment addition congruent segments theorem transitive property of equality subtraction property of equality?

Which point has an coordinates of (2,0) ? a
