Answer:

Step-by-step explanation:
The triangle in the given problem is a right triangle, as the tower forms a right angle with the ground. This means that one can use the right angle trigonometric ratios to solve this problem. The right angle trigonometric ratios are as follows;

Please note that the names ( ) and (
) and ( ) are subjective and change depending on the angle one uses in the ratio. However the name (
) are subjective and change depending on the angle one uses in the ratio. However the name ( ) refers to the side opposite the right angle, and thus it doesn't change depending on the reference angle.
) refers to the side opposite the right angle, and thus it doesn't change depending on the reference angle. 
In this problem, one is given an angle with the measure of (35) degrees, and the length of the side adjacent to this angle. One is asked to find the length of the side opposite the (35) degree angle. To achieve this, one can use the tangent ( ) ratio.

Answer: y=7x 
Step-by-step explanation:
The way I did it was, I looked at the chart. The highest it goes is 30 and 210. So for your answer, you have to multiply. 7x30 gives you 210 and there y=7x
 
        
             
        
        
        
The formula for cosine is adj/hyp. For angle B, 10 is the adjacent and 24 is the opposite. The hypotenuse ( in this case, 26) is the longest side. the ratio for angle b would be 10/26.
