Answer:
Proved Below
Step-by-step explanation:
Hence, Proved that 
is equivalent to 
.
BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees
9
27/9 = 3
54/9 = 6
81/9 = 9
Answer:
I think this will help
Step-by-step explanation:
Make a point at(-5,-6) then go up two boxes and right three boxes.
6 mph.
To find this, create a ratio.
2/20 = x/60
This will allow you to compare here time of twenty minutes to an hour in the same context.
Multiply 2 by 60 and divide by 20 to get the answer of 6 mph.
Thus, Sabrina's average speed in miles per hour is six miles per hour.
Hope this helps!
