Answer:
Step-by-step explanation:
abc = 1
We have to prove that,

We take left hand side of the given equation and solve it,

Since, abc = 1,
and c = 
By substituting these values in the expression,




Which equal to the right hand side of the equation.
Hence, 
we know that
the two triangles in the figure are similar, because they have three equal angles
therefore
The ratio of the corresponding sides are equal

therefore
<u>the answer is the option C</u>

<em><u>Answer: =200</u></em>
Step-by-step explanation:
This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. multiply by the numbers. product it's going to be multiply by the numbers, fractions, factors, and multiples.
5*40=200
40*5=200
200/5=40
200/40=5
Hope this helps!
Thanks!
Have a great day!
That would depend on what x is equal to. So, there's not enough information to fully determine an answer.
