How many numbers greater than zero and less than 50 equal the product of two consecutive positive integers?
spin [16.1K]
Consecutive numbers would be like 2 and 3, or 7 and 8.

All we need to do is keep multiplying pairs of consecutive numbers until we get above 50.

1 × 2 = 2 (that's one.)
2 × 3 = 6 (two)
3 × 4 = 12 (three)
4 × 5 = 20 (four)
5 × 6 = 30 (five)
6 × 7 = 42 (six...)
<em>7 × 8 = 56 > 50</em>
We have a total of 6 numbers that equal the product of 2 consecutive intergers<em>

Simply<br> tan 45°. sin 30° - cot 45°/sec 60°​
dusya [7]

If we want to write the given four numbers in another form, we can write it like this;

tan45=sin45/cos45=1

sin30=sin(\frac{\pi }{2}-60 )=cos60=\frac{1}{2}

cot45=cos45/sin45=1

sec60=1/cos60=\frac{1}{1/2} =2

Now let's rewrite the given expression and get the result.

(tan45.sin30)-(cot45/sec60)=(1.\frac{1}{2})-(\frac{1}{2} )=0
