Simplify Q + S - T.
is the the correct answer
x - y = -2
x - y = - 5
x - y = - 6
With step by step explanation !
It's easier to deal with the symbolic sum (in sigma notation),
Expanding the terms in the fraction, computing the quotient, and decomposing into partial fractions gives
and it's the latter two terms that reveal a telescoping pattern.
In case you need more details about the partial fraction decomposition, we are looking for coefficients a and b such that
or
which gives a = 1, and a + b = 0 so that b = -1.
Our sum has been rearranged as
The remaining telescoping sum is
1/2 [(1/1 - 1/2) + (1/2- 1/3) + (1/3- 1/4) + … + (1/48- 1/49) + (1/49- 1/50) + (1/50 - 1/51)]
and you can see how there are pairs of numbers that cancel, so that the sum reduces to
1/2 [1/1 - 1/51] = 1/2 [1 - 1/51] = 1/2 × 50/51 = 25/51
So, our original sum ends up being
Answer:
PR corresponds to TR
Step-by-step explanation:
<Q and <S are pair of alternate angles [since PQ is parallel to ST]
<Q = <S [since they are alternate angles]
So, PR corresponds to TR [since they are opposite sides of alternate angles and ΔPQR is similar to ΔTSR]
Answer:
PR corresponds to TR.
Step-by-step explanation:
Its the second choice:
PR corresponds to TR.
This is because they are opposite equal angles ( < Q and <S).
