∠C = ∠ D (vertical angles
C= -2x + 90
D= x-30
Since C = D , Then -2x + 90 = x-30
-2x - x = - 30 - 90
-3x = -120
3x = 120 and x = 40°. Now replace x by 40 in any of the equality, say :
D = x-30 ; D = 40 - 30 and D = 10°
Ratio is 5:2:3
2(5:2:3) is 10:4:6
10 cups of pear, 4 cups of pineapple, and 6 cups of plum juice
The f(9) = 1
first you plug in 9, where x is
f(9) = 2/3(9) - 5
multiply
f(9) = 6 - 5
subtract
and you should get f(9) = 1
Yes similar polygons are are two polygons with the same shape but not the same size
