x = number
the equation to use is: 3x+4=28
3x+4=28
3x=24
x-24/3 =8
x=8
You have to turn them into mixed numbers. 10/3 divided by 15/8. Now you have to multiply the first number by the reciprocal of the second. 10/3 times 8/15. The answer is 80/45 or 1 7/9.
We know, tan x = 1 / cot x
So,tan x = 1/ 0.78
tan x = 1.28
In short,Your Answer would be 1.28
Hope this helps!
