2x-9y and 11x + 3y - 12y - 9x
Answer:
(6,-4)
Step-by-step explanation:
P(-2,2)
-2 - 4 = 6
2 - 6 = -4
Answer:
CD = 27
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sided are equal, that is
=
, substitute values
=
= 3 ( multiply both sides by 9 )
CD = 27
y=70(vertically opposite angle)
70+50+X =180 (sum of angles in triangles)
120+x=180
X=60 //
Answer:
x = 60°
Step-by-step explanation:
AOB Center: O AB: diameter
arc ADB = 180°
arc DB = 180 - arc AD = 80°
x = 1/2 x ( arc DB + arc AC) = 1/2 x (80 + 40) = 60°
