Answer:
The first one
Step-by-step explanation:
When you do a reflection across the y-axis, it is like a mirror. And if you have a generic point (x, y) the new point will be (-x, y).
In the table you have 4 points:
(x,y)
(-3,9)
(0,0)
(2,4)
(5,25)
The new points will be:
(3,9)
(0,0)
(-2,4)
(-5,25)

b = 2.77 m
A = 43.0°
C = 111.1°
cosine law to find b

b = 2.7708\ m
Find angle A with sine law
![\displaystyle \frac{\sin A}{a} = \frac{\sin B}{b} \\ \\ \sin A = \frac{a \sin B}{b} \\ \\ A = \sin^{-1} \left[ \frac{a \sin B}{b} \right] \\ \\ A = \sin^{-1} \left[ \frac{4.33 \sin 25.9}{2.7708} \right] \\ \\ A = 43.0467020](https://tex.z-dn.net/?f=%5Cdisplaystyle%0A%5Cfrac%7B%5Csin%20A%7D%7Ba%7D%20%3D%20%5Cfrac%7B%5Csin%20B%7D%7Bb%7D%20%5C%5C%20%5C%5C%0A%5Csin%20A%20%3D%20%5Cfrac%7Ba%20%5Csin%20B%7D%7Bb%7D%20%5C%5C%20%5C%5C%0AA%20%3D%20%5Csin%5E%7B-1%7D%20%5Cleft%5B%20%5Cfrac%7Ba%20%5Csin%20B%7D%7Bb%7D%20%20%5Cright%5D%20%5C%5C%20%5C%5C%0AA%20%3D%20%5Csin%5E%7B-1%7D%20%5Cleft%5B%20%5Cfrac%7B4.33%20%5Csin%2025.9%7D%7B2.7708%7D%20%20%5Cright%5D%20%20%5C%5C%20%5C%5C%0AA%20%3D%2043.0467020)
Find C with angles in triangle sum to 180
A + B + C = 180
C = 180 - A - B
C = 180 - 43.0467020 - 25.9
C = 111.1
1/6*1/6*1/6=1/216
I HOPE THIS HELPS!
#Lets just write x as the nunber you asked
x × 40/100 = 18
x = 18 : 40/100
x = 18 × 100/40
y = 1800/40
y = 45

Answer : 45</h3>
