Answer 6: The value of x is 10 because since angle 3 is 90 degrees angle 1 is 9x 9 times 10 equals 90 degrees which is the same as angle 3 which is 90 degrees, so the answer is 10.
4.) adjacent angles are 2 angles that share a common side AND vertex <=angle ANSWER- <3 & <2, < 5& <1 5.) Vertical angles are angles that are made by 2 intersecting lines<=angle ANSWER- <1 &<3, 6.)90=9x divide both sides by 9 and x=10
