Sin D is 21/29
cos D is 20/29
tan D is 21/20
sin E 20/29
cos E is 21/29
tan E is 20/21
sin is y/r
cos is x/r
tan is y/x
Two different perspectives of the triangle, D and E.
Answer:
This is not proportional. In order for it to be proportional the number from dividing y/x must be the same all the way through. Example:18/2=9 20/4=5
The answers are not the same, therefore x and y are not proportional. Hope this helped.
Step-by-step explanation:
All steps that Marcie did are right, but she forgot to change sign in last step.
Consider the inequality
Then
Group the numbers:
Separate terms with x and without x in different sides:
The coefficient at x is -8 and it is negative, then dividing the inequality by -8 you have to change sign in opposite:
Answer: Marcie forgot to change sign in last step.
Answer:
The variable "m" is the variable for SLOPE, and the variable "b" is the variable for the Y-INTERCEPT.
Hope this helps!
Answer: It would probably be 30
Step-by-step explanation:
The ratio is 10:0 , 20:10 , 30:20 , 40:30 , 50:40, 60:50 , etc…
so basically you just need to know the ratios!
Hope I could help :)
