I need help with these four problems. http://oi41.tinypic.com/6sb97c.jpg
NO.(30) x+67 = 180 (supplement angles) solve for x = ... while abviously that y = 67 (alternate exterior angles)
looks still incorrect for angle y --" i mean, y = x (alternate exterior angles)
What do you mean by is still incorrect?
For number 31 do you do the same!
i mean i have mistaken by take equation y = 67, that should y = x so, if you get x, sure you get x too
for No.31) x+109 = 180 (consecutive interior angles) solve for x and y = 109 (opposite angles)
have you cleared for No.30 and 31 ??
ok, let's go to no.32 3x - 1 = 89 (corresponding angles) solve for x
30. Angle x = 180-67=113, angle x = angle y because they are alternate exterior angles. 31. Angle x = 180-109= 71 because they are same side interior angles. Angle y = 109 because vertical angles are congruent.
32. 3x-1=89 because corresponding angles are congruent. x=30
33. 13x-5+94=180 because vertical angles are congruent and because same side interior angles are supplementary. x = 7
I didn't get seven I keep getting a decimal
What is -5 + 94?
Subtract 89 from both sides of the equation.
Thank you very much for your help ^_^
