Answer:
x = 2.4
Step-by-step explanation:
For this equation, you need to use trigonometry. we only need to use one of the two angles given and for this example i'm going to use the 60° angle. as we know the adjacent side and want to know the opposite side, we need to use the trig ratio tan
in this case, we will replace the adjacent side with
the square root of 2.
= 
as the side we know is on the bottom of the ratio, we need to multiply it by the ratio (tan) then the angle (in case you don't know, * means multiply)
round to 1 decimal place
x = 2.4
Hope this was helpful :-)
I'm sorry if this was confusing, trigonometry is very hard to explain.
Answer:
Step-by-step explanation:
Four more than zero, and Positive four because four above zero is saying that its a positive number. (positive numbers are always greater than zero) so it would be positive four, and Four more than zero.
I am going to use C to represent cookbook and N to represent N. I find that easier to remember which is which.
Day 1: 5C + 3N = 167
Day 2: 3C + 1N = 89
We need to solve one of these equation for either the C or N. I always choose the easiest one! Day 2 looks like the one.
3C + 1N = 89 (I am doing to solve for N because we won't have a fraction)
1N=89-3C
N=89-3C
Now we take this solution for N and put it into our first equation.
5C + 3(89-3C) = 167 (We need to distribute)
5C + 267 - 9C = 167 (Use subtraction to move C values to the right and numbers to the left)
267-167 = 9C-5C
100 = 4C
25 = C $25 for the Cookbooks.
Now, we have to go back and solve for N by putting $25 in for C in the second equation.
N=89-3(25)
N=89-75
N=14 dollars for each novel.
Check by putting both back into the first equation:
5C + 3N = 167
5(25) + 3(14) = 167. It checks out!
where is your triangle mate??

We need to convert given value 465^8 as the base 5 number.
Let us assume x is the exponent of 5 when we take base 5.
We can setup an equation now.
5^x=465^8
Taking ln on both sides, we get





On simplifying, we get

Therefore,
