The value of the variable is 4√5. Then the correct option is C.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The similar triangles are shown in the diagram.
16 / x = x / 5
x² = 16 × 5
x = 4 √5
Then the value of the variable is 4√5.
Then the correct option is C.

Answer:
Combination
Step-by-step explanation:
Here by 10C7 we actually mean, 
And the formula for evaluating mCn is
Therefore
10C7 =
Where m! is called m factorial and can be evaluated as
m!= m*(m-1)*(m-2)*(m-3)*.......3*2*1
Hence
10!= 10*9*8......*3*2*1
7!= 7*8*6.....3*2*1
3!=3*2*1
With these we can evaluate
10C7
Hence the answer is D
Group like terms then
add like terms
d-2d-10+7=8-10+d
-d-3=-2+d
add d to both sides
-3=-2+2d
add 2 to both sides
-1=2d
divide both sides by 2
-1/2=d
