A. (Area of triangle UVW)/(Area of triangle RST)=3^2=9
B. Substitute Area of triangle RST=9 into the equation above.
(Area of triangle UVW)/9=9
Area of triangle UVW =9x9=81 cm^2
Answer:
the first one is -4.6
Step-by-step explanation:
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.
This is the process I would use:
Maddy's = 2x 2x+x=15
Meg's = x 3x=15
x=5
Since Maddy's is 2x, multiply the 5 times 2 and you find that Maddy has 10 stickers.
