Answer:

A choice

Step-by-step explanation:

sec is defined as 1/cos.

cos is again defined as adjacent to hypotenuse.

We know that adjacent is x and hypotenuse is r.

Therefore:- cos is x/r

Now sec is 1/cos = 1/(x/r)

1 ÷ x/r is 1•r/x

the sum of the reversed number and the original number is 154. Find the original number, if the ones digit in it is 2 less than

VladimirAG [237]

Answer:

The number is 86

Step-by-step explanation:

Let the number be $xy$ , then the reverse is $yx$

The sum of the reversed number and the original number is 154,

$\implies (10x+y)+(10y+x)=154$

We simplify this to get:

$\implies 11x+11y=154$ ....eqn(1)

If the ones digit in it is 2 less than the tens digit, then

$y=x-2$ ....eqn(2)

Putt equation (2) in (1)

$\implies 11x+11(x-2)=154$

$\implies 11x+11x-22=154$

$\implies 11x+11x=154+22$

$\implies 22x=176$

$\implies x=8$

Put x=8 in the second equation:

$y=8-2=6$

The original number is 86
