3. We can see that
1+100=101
2+99=101
3+98=101
.................
and so on
From 1 to 100, there are 50 pairs that has the sum is 101
Z=101×50=5050
4. We can see that
1-2=-1
3-4=-1
5-6=-1
...........
and so on
There are 10 pairs that has sum is -1
Z= 10×(-1)=-10
Answer:
see explanation
Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+
=
, that is
1 + cot²θ = cosec²θ ← as required
if u like it,u can start following me...
Answer:
10x-8=b
--------(over)
ax
Step-by-step explanation:
2 (5x-4) = ax +b
distrbute 2
10x-8=ax+b
divide each side by ax
10x-8=b
--------(over)
ax
I think
They are opposite side interior angles and they are exactly the same degree
