Step-by-step explanation:
30% of the money was equal to 51
so:
Perimeter of a square formula: 4s, where s is one side.
perimeter = 60
4s=60
s=15
One side is 15 centimeters
the radius is half of a side
r =
r=7.5
r = OP
OP = 7.5
perimeter = 60
4s=60
s=15
One side is 15 centimeters
the radius is half of a side
r =
r=7.5
r = OP
OP = 7.5
Answer:
B.11
Step-by-step explanation:
Two triangles are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.
From the image, CF corresponds to EF, CD corresponds to EG and DF corresponds to GF.
DF = DE + EF = 7 + 5 = 12
Since Triangle CDF is similar to triangle EGF. hence:
We can see that:
CF = CG + GF (line segment addition postulate)
CF = x + 4
15 = x + 4
x = 15 - 4
x = 11
