Answer:
20+2x
Step-by-step explanation:
If you're just looking for an expression, then it would be 20+2x considering there's no way to solve for x, and there's 2 widths and 2 lengths of a rectangle
I believe the answer is b
Answer:
46.66%
Step-by-step explanation:
42/90 = x/100
find x
multiply 42 times 100 and divide by 90
Answer:
(0, 6), (4, 4), and (0, -4)
Step-by-step explanation:
basically you pick 2 sides (each with endpoints at two of the three verticies) to be the adjacent sides, and then you can easily find the fourth vertex for each case.
Answer:
x = 50
m∠D = 150°
m∠F = 30°
Step-by-step explanation:
- supplementary angles are two angles whose sum is 180°
∠D + ∠F = 180°
3x + x - 20 = 180
3x + x = 180 + 20
4x = 200
x = 200/4
x = 50
D = 3*50 = 150
∠D = 150°
F = 50 - 20 = 30
∠F = 30°
