Answer:
Step-by-step explanation:
Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:
and cross multiply to get
21x = 126 and
x = 6
We can use the SSS congruence theorem to prove that the two triangles in the attached figure are congruent. The SSS or side-side-side theorem states that each side in the first triangle must have the same measurement or must be congruent on each of the opposite side of another triangle. In this problem, for the first triangle, we have sides AC, CM, AM while in the second triangle we have sides BC, CM, and BM. By SSS congruent theorem, we have the congruent side as below:
AC = BC
CM = CM
AM = BM
The answer is SSS theorem.

Answer:

Step-by-step explanation:
We know that for principal amount P , time period T and rate of interest
, simple interest is given by
.
Here ,

To find : simple interest rate i.e., 
On putting values of
in formula , we get 

Now we need to round off the answer to the nearest tenth .
So, simple interest rate is % =
=
