Answer:
the nearest whole number is 133
880, theres no change in between, only after every 13 years
The two numbers are 41 & 37.
The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):
(x) + (x + 4) = 78
Now, we need to simplify it (combine like terms):
2x + 4 = 78
Then you can solve it like any other equation. Subtract 4 on both sides:
2x = 74
Divide by 2 on both sides:
x = 37.
So, now you know one number is equal to 37 and that the other is 37 + 4.
That's how you get 37 & 41.
To ease your live re write each one by using sin, cos, tan, knowing well that:
cscx = 1/sin x ( sin of an angle = opposite side/hypotenuse(23)
secx = 1/cos x (cos of an angle = adjacent side/hypotenuse(23)
cotx = 1/tanx (tan of an angle = opposite side/adjacent side)
Work it out & if you have difficulties do let me know
