Answer:
Step-by-step explanation:
let width=x
length=3x
area=x*3x=3x^2
so 3x^2=10

Answer: I know D it’s 18.6
Answer:
x = 16°
H = 46°
I = 55°
J = 39°
Step-by-step explanation:
Since the whole figure is 180°
Deduct 180 by the numbers mentioned above in order to find x.
180 - 2 - 9 - 9 = 160
3x + 4x + 3x = 10x
10 x = 160
x = 160 ÷ 10 = 16
Since we know what x is, we can find all the angles in the figure.
Angle at H = 3 x 16 - 2 = 46°
Angle at I = 4 x 16 - 9 = 55°
Angle at J = 3 x 16 - 9 = 39°
Answer:
I dont understand your question but I'm going to assume that you want to add those numbers the answer would be 37 marbles in total
