Solve for x

x = 54

Step-by-step explanation:

These angles are complementary because they add up to 90:

x - 7 + 43 = 90

x + 36 = 90

x = 90 - 36

x = 54

Step-by-step explanation:

Since the total of the two degrees makes a right angle, we know that the unknown degree has to be 47

Knowing this, we can add 7 to this. (This is the inverse of subtracting to eliminate 7)

47 + 7 = 54

So x = 54

We can verify by solving replacing x.

(54 - 7) = 47

47 + 43 = 90

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
