Answer:
y/x =2/3
Step-by-step explanation:
you just need see at one point. for example: (3, 2)
Answer:
y = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = 
sin45° = 
= 
Multiply both sides by y
y × sin45° = 9, that is
y × = 9
Multiply both sides by
y = 9
Surprise, there 8 letters.
So, 8*7*6*5*4*3*2*1= 40, 320
This will leave you with
140 = 2(40) + 2x
60 = 2x
30= x
So the length is 30.
