Answer:
You can always ask the tutor they give the correct answer :))
The the first one the answer should be -4
For the second one the answer should be 3
We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

then, solving for b, we get:

now that we have that b = 41, we can find the measure of each angle:
The price will decrease by $2132
<u>Step-by-step explanation</u>
Given that the next model of the sports car will cost 5.2% less than the current model.
The price of the current model=$41000
The price of the next model will be 5.2% less than $41000


There is a $2132 decrease in prize of the sports car.
If two triangles are similar then the
corresponding sides are in proportion. Thus,
AB / AU = BC / UV = AC / AV
AB / (20x+108) = 703 / 444
Where AB is equivalent to:
AB = AU + UB
AB = 20x + 108 + 273
AB = 20x + 381
Therefore going back to the first equation:
(20x + 381) / (20x + 108)
= 703/444
444 (20x + 381) = 703 (20x + 108)
8880x + 169164 = 14060x + 75924
14060x - 8880x = 169164 – 75924
5180 x = 93240
x = 93240 / 5180
