It's 12/35 because tangent is opposite over adjacent, so 12 is opposite of angle M and 35 is adjacent of angle M
If you want to remember cosine, sine, and tangent just remember

1= 22.08
2= 25704
3= 587
4= 610
If you plug in the x-coordinate into your equation for the line, you get
y = -3(4)/4 + 3
y = -3 + 3
y = 0
Let x be the amount of Ann money, y be Jessica's money and z Mary money.
30% of z equates 0.3*z.
Ann has 30% less than z so: x = z - 0.3z = 0.7z.
70% of z equates 0.7z.
"Jessica has 70% more than Mary " we deduce the equation: y =z+0.7z= 1.7z.
Signe the total is $102, we deduce the equation x+y+z = 102.
x=0.7z and y=1.7z then 0.7z+1.7z+z=102, therefore 3.4z=102 then
z =102/3.4 = $30.
x=0.7*30= 21 and y=1.7*30=51.
Ann has $21, Mary has $30 and Jessica has $51.
Answer:
23 inches
Step-by-step explanation:
Circumference = 2πr
72 = 2×3.142×r
Divide through by 2 × 3.142
r = 
r = 11.458 inches
Diameter = 2r
Diameter = 2* 11.458 = 22.92
= 23 inches to the nearest inch
