Step-by-step explanation:
To find cscθ we require to find the third side of the triangle.
let 3rd side be x and using Pythagoras' identity
x² + 8² = 9²
x² + 64 = 81 ( subtract 64 from both sides )
x² = 17 ( take square root of both sides )
x = 
Then
cosθ = 
= 
cscθ = 
= 
tanθ = 
= 
Lets think they have cards, Alex = x , Gil = y and Meg = z. Then,
x+y+z = 740
Alex had 20 fewer cards than Gil. So,
x+20 = y
Alex had 120 fewer cards than Meg. So,
x+120 = z
x+(x+20)+(x+120) = 740
3x + 140 = 740
x= 200
y= 220
z= 320
<span>So Alex had 200 cards, Gil had 220 cards and Meg had 340 cards</span>
Answer:
Answer: Expression that represents the length of one side of the square is x - 5.
It spins tilted on its axis, it spins every hour that's why we have 24 hours, day to night
