Answer:
Step-by-step explanation:
we know,
The Angle Addition Postulate states that: If a point lies in the interior of an angle, then the postulate describes that putting two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles.
Here, W is the internal point.
The two angles are UVW and WVX.
Now, by the angle addition postulate,
UVX is equal to the sum of UVW and WVX.
Hence, the reason is-

Step-by-step explanation:
u just have to add all of them together
Answer:
The circumference appears four times larger.
Step-by-step explanation:
C=2πr
So if we are multiplying the radius (r) by 4 then that would most definitely increase the outcome (circumference) by 4
here's why:
C=2πr
C=2π(4r)
C=8πr
So,
8πr/2πr = 8/2 = 4
Hope this helps! ;)
Answer:
Laptop: $2,270
Desktop: $1,820
Step-by-step explanation:
Let L identify the laptop price and D the desktop price.
We can first say:
L = D + 450 ( the laptop cost $450 more than the desktop)
Then we can say:
0.09 D + 0.06 L = 300 (The total finance charges for one year were $300)
Then we substitute L by its value from first equation into the second equation:
0.09 D + 0.06 (D + 450) = 300
0.09 D + 0.06 D + 27 = 300
0.15D = 273 (removed 27 on both sides, and simplified left side)
D = 1,820
The cost of the desktop was $1,820
The cost of the laptop was $2,270 (price of desktop + $450)
