c is the correct answer
Answer:
12/12
Step-by-step explanation:
6/12= 1/2
so 1/2+1/2 = One Whole and that the same thing as 12/12
Answer:
Step-by-step explanation:
Remember that
Area of Circle =

They told us that for this circle, the area is 
If you put it back into the formula for area of a circle we get:
Area of Circle =

Divide both sides by
.
144 = 
Now we want to solve for r (r = radius).
You need to square root each side


So now we know the radius,
metres
Also remember that
Diameter = 
So,
Diameter = 2 times 12 = 24 metres
Answer:
See Image below:)
Step-by-step explanation:
You can use the app photo math, you just take a picture of the question and it shows you the steps.
A straight line is 180°, so you can do:
109 + ? = 180 (? is the top angle of the triangle)
? = 71°
Because the triangle is an isosceles triangle, the other angle is 71° too.
71 + 71 + ? = 180
? = 38
You subtract 38 with 90 to find the other angle.
90 - 38 = 52°
To find ∠2 you subtract 52 with 180.
180 - 52 = 128
∠2 = 128
128 = 11x + 18
110 = 11x
10 = x
