Answer:
9, 10, 3 and 1/3
Step-by-step explanation:
21 = 7 x 3
Therefore divide each side of the larger triangle by three to get the smaller one.
27/3 = 9
30/3 = 10
10/3 = 3.33333...
Answer:
45.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship ...
Sin = Opposite/Hypotenuse
Filling in the given information, you have ...
sin(V) = 6.6/9.2
V = arcsin(6.6/9.2) ≈ 45.8395°
∠V ≈ 45.8°
_____
It can help to draw a diagram of the triangle, so you can see the letter designations of adjacent and opposite sides and the hypotenuse.
Answer:
The area of the shaded region is 
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
we have
assume
substitute the values
Answer:
x=0
Step-by-step explanation:
x+2/5=6/15
x+2/5=2/5
x+2/5-2/5=2/5-2/5
x=0
420 miles on 12 gallons
x miles on 8 gallons
420/x = 12/8
use cross multiply
420*8 = 12*x
3840 = 12x
x = 3840/12
x=320
