Answer:
D
Step-by-step explanation:
The two graphs are reflections of each other in the y-axis
If one is f(x), other is f(-x)
c^x = b^(-x)
c = b^-1
c = 1/b
Length of x is 98.2 m
<u>Step-by-step explanation:</u>
Step 1:
Use the trigonometric ratio tan 27° to find the common side of both the right angled triangles.
tan 27° = opposite side/adjacent side = opposite side/9
∴ Opposite side = 9 tan 27° = 9 × - 3.27 = -29.46 m
Step 2:
Use this side and trigonometric ratio cosine to find the value of x.
cos 49° = adjacent side/x = -29.46/x
∴ x = -29.46/cos 49° = -29.46/0.30
= 98.2 m (negative value neglected)
2/5 plus 27/9 minus 0 equals 0
