Find the value of x. round to the nearest tenth. tan 46 = x/12

 Hello there!

we have the equation tan(46) = x/12

(here I assume that the 46 is in degrees)

and we want to find the value of x.

We need to isolate x on one side of the equation, we can do it by multiplying by 12 in both sides of the equation:

tan(46°)*12 = (x/12)*12 = x

then x = tan(46°)*12 = 12.426

And we want to round it to the nearest tenth.

The tenth is the first number after the decimal point, in this case, is a 4.

To round the number we need to look at the following number, if it is 5 or bigger, we need to round up, if the following number is smaller than 5, we need to round down.

The next number to the 4, is a 2, this means that we need to round down:

this means that the solution is x = 12.4

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
