90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12

90 + 90 + 60 = 240

54 + 560 + 90 = 704

90 minus 75 =15 therefore 15 + 75 = 90

54 + 560 + 90 = 704

To solve for tan x degree 90 you do a few things. First, if x equals 90, then this equals 1.5597 radian or 89.36 degrees. This is the easiest way to solve tan x degree 90.

The answer is .90. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.

6 + 90 = 96

To find the missing number in the denominator of the fraction, you can set up the equation 90/x = 18, where x is the missing number. To solve for x, you would multiply both sides by x to get rid of the denominator, giving you 90 = 18x. Then, divide both sides by 18 to solve for x, which equals 5. Therefore, the fraction is 90/5 = 18.
