Answer:

x = 30 degrees

Step-by-step explanation:

These triangles are perfectly symetrical. This is shown by the length of sides given in the problem. Since the triangle is symetrical, E is equal to B just as D is equal to C. Since B is 30 degrees, we can tell that E is also 30 degree.

The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function $f(x)=4.7^x$ for x = - 1 and x 2.

The solution is:

1) For x = - 1

$f(-1)=4. 7^{-1} =4. (1/7)=4/7$

2) For x = 2

$f(2)=4.7^2=4(49)=196$
