Find x

A: 11.2
B: 13.1
C: 9.2
D: 22.9

Hi there!

We can also use the other angle but I will focus on 35°.

The reason why we use the equation above because tan is equivalent to opposite/adjacent

From the picture, the opposite is x-term while the adjacent is 16 if we focus angle 35°.

Define theta = 35°. Thus, the equation would be tan35° = x/16.

Solving the equation, you might want to bring open Trigonometric Table or a calculator to calculate tan35°. You should get 0.7 (rounded)

Then solve the equation for x-term.

Hence, the value of x is 11.2

Furthermore, you can also use the other angle. If we use 55° instead, the equation would be tan55° = 16/x. The outcome would be the same.

Hope this helps, and Happy Learning! :)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
