Answer:
H. 26°
Step-by-step explanation:
Two facts from geometry come into play here:
- alternate interior angles are congruent where a transversal crosses parallel lines
- the exterior angle of a triangle is equal to the sum of the remote interior angles
__
The second of these relations tells us the exterior angle at X of triangle XDE (where X is the point the diagonals cross) is equal to the sum of angles D and E of that triangle. That is, ...
50° = ∠FDE +∠GED
∠FDE = 50° -24° = 26°
The second of the relations described above tells us that angles FDE and DFG are congruent.
∠DFG = ∠FDE = 26°
Simplifying
9 + -2x = 35
Solving
9 + -2x = 35
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + -2x = 35 + -9
Combine like terms: 9 + -9 = 0
0 + -2x = 35 + -9
-2x = 35 + -9
Combine like terms: 35 + -9 = 26
-2x = 26
Divide each side by '-2'.
x = -13
Simplifying
x = -13

We were told that:
therefore to see if it is correct you can just input the values for x and y and see if they add up to 6 (add the vertical values). For example;when x = 1, y = 5 or when x = 2, y = 4
Answer:
x = 50°
Step-by-step explanation:
According to exterior angle property of a traingle , measure of exterior angle is equal to sum of it's two interior angles of the triangle. So,
