Answer:
Cos A = x/z
Step-by-step explanation:
You need to memorize the definitions of all the trig functions and then these types of problems become easy! OK?
Cos = adjacent side/hypotenuse
Cos A = x/z
You solve for a variable in an equation by taking the variable to one side of the equation and other terms to the other side of the equation using arithmetic properties.
The answer is x equals 17
Answer:

Step-by-step explanation:
Given

Required
Select numbers part of the solution
O 4.7 O 5.1 O 7.4 O 8.2 O 9.6
implies that, the value of t cannot exceed 7.4.
So, we have:
4.7, 5.1 and 7.4 in this range
<em>However, 8,2 and 9,6 do not belong to this range</em>
