Answer:
A) ERROR
B) ∠C = 26°
Step-by-step explanation:
Houston, We have a problem!!! too much information
If we had a legit triangle, the law of sines would hold
19/sin138 = 8/sin20
28.395 = 23.390
as this is NOT an equality, the triangle does not exist as described.
IF it did, we'd get different results depending on which set we used
∠F = 180 - 138 - 20 = 22°
Law of sines
19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>
or
8/sin20 = DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>
If we attempt to use Law of cosines
DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>
so really none is correct because we attempt to use trig calculations to a non-triangle.
12) AC² = 15² + 19² - 2(15)(19)cos120
AC = 29.51270...
29.51270 / sin120 = 15/sinC
C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>

Answer:
year 6.6025 if there is no typo in your question and numbers are right.
Step-by-step explanation:
G = 63205 + 2500x
S = 50000 + 4500x
since 9% of 50000 = 0.09(50000) = 4500
find when G = S
63205 + 2500x = 50000 + 4500x
subtract both sides by 2500x to move x terms to the right
63205 = 50000 + 2000x
subtract both sides by 50000 to move the number to the left, so we can get like terms on each side
13205 = 2000x
divide both sides by 2000
x = 6.6025
