Question

solve this question number 6

Answer 1

We can easily solve Angle 1 and Angle 2.
That is because they form a lineal pair and it equals 180 derees.
Let the ratio be 5x : 7x, add them becomes 12x
Solve for x by diving that to 180, which is 180 / 12 = 15 = x
That means your..
Angle 1 =75 and
Angle 2 = 105

Since we found out both angles, Angle is 3 simple because it is a Vertical Angle of Angle 1 therefore Angle 1 and Angle 3 is congruent, that means it is equal to 75.

Angle 8 is an Alternate Exterior Angle of Angle 2 therefore they are both congruent so Angle 8 is 105.
