I will give brainliest to whoever got the right answer first, so please get it right, help me do number 25, number 26, and number 27, remember and please, READ THE DIRECTIONS.
25. 16x + 9x + 5 = 180 because the angles are supplementary. 25x + 5 = 180 25x = 175 x = 7 Now because there are vertical angles, it is easy to find the value of y. 4y = 9(7) + 5 4y = 63 +5 4y = 68 y = 17
26. 6x - 11 + 2x - 9 = 180 because the angles are supplementary. 8x - 20 = 180 8x = 200 x = 25 Now because there are vertical angles, you can find the value of y. 6(25) - 11 = 20y + 19 150 - 11 = 20y + 19 139 = 20y + 19 120 = 20y y = 6
27. 9x + 2 + 10x + 7 = 180 because the angles are supplementary. 19x + 9 = 180 19x = 171 x = 9 Again, there are two vertical angles. 10(9) + 7 = 18y + 25 97 = 18y + 25 72 = 18y y = 4
