Triangles ABC and DEF are similar, which means corresponding sides occur in ratios with one another. Mathematically, this means
Also, corresponding angles are congruent. These are A and D, B and E, C and F.
As an example, for 21, the above equation turns into
and you can solve for and directly:
The others are solved exactly the same way. In each case, you happen to be given all the side lengths for one of the triangles, and one of the side lengths for the other triangle. So all you need to do is plug in what you know and solve for the remaining two sides.
Answer:
f(x)=60c * 24h
Step-by-step explanation:
Hope this helped!
1.) 4, 2, 1, 1/2, 1/4,... 2.)2, 6, 18, 54, 162, ...
3.) -4, -16, -64, -256, ... are geometric sequences because common ratio is same. Example: 1.) ratio of 1st and 2nd term is 1/2. Similarly ratio of 3rd and 4th term is 1/2 and so on.
Answer:
A. Nonnegative
Step-by-step explanation:
By definition, the absolute value of any number must be positive (i.e non-negative).Hence A is the answer.
