Answer:
once you find 3/4 of 1200 you will know the answer
Step-by-step explanation:
3/4 of 1200
x + 5+x+7+Х=42units
3x=42-12
x=30/3
x=10
x=16/113
look at them in order
Sin(A) = opposite/hypotenuse = 12/13
Cos(A) = adjacent/hypotenuse = 5/13
Tan(A) = opposite/adjacent = 12/5
1/2652
1/52*1/51=1/2652
