What is the value of x in the figure? <br><br><br> x= ?
Otrada [13]
X = 68

Since the angle opposite of it is a right angle, we know that 22 + x has to equal 90 also. 

So just take 90 - 22 = 68 degrees

The area of a circle is 100 square miles. What is the diameter?
adell [148]

Answer:

The diameter of a circle with an area of 100 square miles is 20/√π miles.

Step-by-step explanation:

Area =100 = πr^2.

diameter = d = 2r.

100 = πr^2.

100/π = r^2.

√(100/π) = r.

10/√π = r.

d = 2r.

d = 2 * 10/√π.

d = 20/√π

What number it can be ?
forsale [732]
I think it could 78  because well i dont think it is right but try if you take away 10 from 16 you would get 6 then if you add 20 to 68 you would get 88 and if you you take away 100 from 88 you would get the 78 and then you would add 20 so you would get 98
