Answer:
39 degrees
Step-by-step explanation:
- by seeing the diagram in the attachment, we can see that the angles UWV and VWX are on straight line or, their sum makes 180 degrees.
- we also know that sum of the angles in a triangle is 180 degrees.
by using the first statement,
UWV + VWX = 180
UWV + 6x-3 = 180
UWV = 180+3-6x
= 183-6x
by using second statement,
UWV+WVU+VUW=180
substituting the values,
183-6x+2x+5+x+13=180
201-3x=180
substracting 180 from both sides,
21=3x
dividing both the sides by 3,
7=x
the angle VWX=6x-3
substituting 7=x,
VWX=6(7)-3= 39.

Answer:
The total number of automatic transmission car dealership sell = 728
Step-by-step explanation:
Given as :
Let the total number of standard transmission car = S
And the total number of automatic transmission car = 200 + S
The percentage of blue standard car = 15%
The percentage of blue automatic car = 10%
Total number of blue car sold = 152
∴ 15% of S + 10% of ( 200 + S ) = 152
Or, 15 S + 10 × ( 200 + S ) = 152 × 100
Or, 25 S = 15200 - 2000
Or, 2 5 S = 13200
∴ S =
So, S = 528
I.e The total number of standard transmission car = S = 528
And the total number of automatic transmission car = 200 + 528 = 728
Hence The total number of automatic transmission car dealership sell = 728 Answer
