Find the ratio of the common sides:
20/50 = 0.4
24/60 =0.4
The unknown side is 0.4 times the known side.
AC = 30 x 0.4 = 12
<span>C) r= d/2
that's the answer</span>
Answer:
(Choice A) 2(3d+3) & (Choice C) (3d+3)+(3d+3)
Step-by-step explanation:
<--- A is correct
< --- B is NOT correct
by associative and commutative properties
so C is correct
A and C are both correct.
Answer:
The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is .
Step-by-step explanation:
We are given the area of an Equilateral triangle which is A = . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
So, the area of an equilateral triangle =
where, s = side of an equilateral triangle
A =
Cross multiplying the fractions we get;
Now. moving to the right side of the equation;
Taking square root both sides we get;
Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
