AC = 30 mm (millimeters)
CF = 20 mm (millimeters)
EG = 0.1 m (meters)
The last question only had one “m” so I’m assuming it’s meters
The answer is b, f[c(p)]=0.9265p.
f[c(p)]=f(0.85p)=1.09(0.85p)=0.9265p
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
