Answer(s):
If you are asking for the equation, it's 9(x+4)=2
However, if you're asking for the value of x as well, it's -34/9
Step by Step:
1) First we must find the equation. In your question, the unknown number is x. Therefore we can know that "the sum of a number and 4" is (x+4). Since we are multiplying this sum by 9, we can put the 9 in front of this expression to multiply it--getting 9(x+4). And since we know it "is 2" we can say that 9(x+4)=2.
2) Now, we have to solve the equation, 9(x+4) = 2
3) We can start by distributing, 9x+36 = 2
4) Now let's move 36 to the right by subtracting from both sides, 9x = -34
5) To isolate x, let's divide both sides by 9, x = -34/9
6) Our fraction answer can't be simplified, so we get x = -34/9

Answer:
x ≈ 29.4 ft
Step-by-step explanation:
The model is a right triangle.
Using the tangent ratio
tan40° = 
= 
( multiply both sides by 35 )
35 × tan40° = x , then
x ≈ 29.4 ft ( to 1 dec. place )
