Answer:
Step-by-step explanation:
Use this to remember the trigonometry ratios:
SOH-CAH-TOA
Because:
Sine=Opposite/Hypotenuse → SOH
Cosine=Adjacent/Hypotenuse → CAH
Tangent=Opposite/Adjacent → TOA
Use the inverse of the tangent ratio since you need to find the angle measure.

Similar means angles are the same
Congruent means angles and sides are the same.
Sail 1 and sail 2 have the same angles but the sides are not the same.
So sail 1 and sail 2 are similar.
Answer:
C, assuming you left off the y on the 30
Step-by-step explanation:
30(.5x-2)+40(.75y-4)
Distribute
15x-60+30y-160
Simplify
15x+30y-220
Cupcakes —> x
Flies —> y
y-x=1 ————1
x-y/2=1 ———1
y-x=x-y/2
2x=3y/2
4x=3x
x=3y/4
Substitute x in For 1
y-3y/4= 1
y/4=1
y= 4
x=3
