Answer:
A. 70°
Step-by-step explanation:
There are two ways to solve this problem:
(1) The sum of all the angles of a quadrilateral equals 360°.
The equation for this problem would be:
110° + 110° + 70° + m∠A = 360°
Simplify:
290° + m∠A = 360°
m∠A = 70°
(2) Trapezoid ABCD is an isosceles trapezoid, because m∠B and m∠C, opposite angles of the same base of the trapezoid, are congruent.
Therefore m∠A and m∠D must also be congruent.
m∠A = m∠D = 70°
We know m = 5, x = 3, and y = -2, and that the point slope form is y = mx + b, so plugging these in we can solve for b;
-2 = 5 * 3 + b
-2 = 15 + b
b = -17
So the equation for the line would be;
y = 5x - 17
b is the y intercept, so that is answered (0,-17), to solve for the x intercept you have to plug 0 in for y in the equation, so;
0 = 5x - 17
17 = 5x
x = 17/5
So the x intercept would be (17/5,0)
