Whats the math you need help with?
It is 27 you add 10 and 27 which equals 27.
I believe the answer is -(2+x)/(2x-4)
Answer:
The second one (answer of 3), but the other ones could've worked, they were just calculated wrong.
Step-by-step explanation:
Here's why each one did or didn't work:
First answer- you had the right idea by cancelling out the two in the denominator, however if you're going to divide 2, you have to divide it from everything in the equation. Meaning you would divide 4 by 2 to get 2, and then add the 1 + 2 to get final answer 3.
Second answer- since you added the numerator separately and then did the basic division, this worked.
Third one- similarly to the first one, you would have to also divide the 2 by 2 to get 1, then adding 1 + 2 to get 3.
Answer:
x ≈ 34.28
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan29° = 
= 
( multiply both sides by x )
x × tan29° = 19 ( divide both sides by tan29° )
x = 
≈ 34.28 ( to the nearest hundredth )
