So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.
x+109+x+89=180
add the numbers and x's together
2x+198=180
subtract 198 from each side
2x = -18
divide each side by 2
x = -9
Put -9 in for x in the equation x+89 to find that angle
-9+89
=80
ANSWER:
That angle equals 80°
Answer:
8.43 years
Step-by-step explanation:
Given data
Cost price P= $4995
Rate r= 10%
FInal amount A= $2150
The expression for the time/duration is given as
t= ln(A/p)/r
t= ln(2150/4995)/0.1
t= ln(0.430)/0.1
t= 0.843/0.1
t= 8.43
Hence the time it will take is 8.43 years
Answer:
c
Step-by-step explanation:
The equivalent to that is 8.
To convert a fraction to a decimal, divide the numerator by the denominator (divide the top by the bottom)
