A bc the opposite of zero is -0, but it cannot be negative so a
Answer:
(- 5, - 2 )
Step-by-step explanation:
Under a clockwise rotation about the origin of 90°
a point (x, y ) → (y, - x ), thus
(2, - 5 ) → (- 5, - 2 )
I think the answers is 40%
1) 2x + 7 = 3x - 7 (If II, corr. angles congruent)
-x = -14
x = 14
2x +7 + 12y + 1 = 180 (Linear Pair)
2(14) + 8 + 12y = 180
36 + 12y = 180
12y = 144
y = 12
2) Corresponding Angles
3) 3x + 5x - 36 = 180 (If II, then s. s. int. angles supp.)
8x = 216
x = 27
4) The third one is false
5) Let x = third angle in triangle
158 + x = 180 (Linear Pair)
x = 22
90 + 22 + m<1 = 180 (Triangle Angle Sum Theorem)
112 + m<1 = 180
m<1 = 68
Hope this helps!
