So to solve this question, just add up all the three angles (ignoring the second pair of the same angle)
So for example:
A) 
So that equals to 180, and so it is not the answer choice since the triangles would have similar angles.
B) 
Also not the correct answer choice.
C) 
Also not the correct answer choice.
D) 
So this triangle will not have similar angles, thus your correct answer! :)
Answer:
for x >0
f(x)=5^x
f(1) = 5^1 = 5
f(2) = 5^2 = 25
f(3) = 5^3 = 125
f(4) = 5^4 = 625
Step-by-step explanation:
From x=1 to x=5
x=1 is starting time
x=time
y=mx+b
m=slope
b=yintercept
slope=(y2-y1)/(x2-x1)
for points (x1,y1) and (x2,y2)
(1,52000) and (5,116000)
slope=(116000-52000)/(5-1)=64000/4=16000
y=16000x+b
find b
(1,52000)
52000=16000(1)+b
52000=16000+b
minus 16000 from both sides
36000=b
the equation is
y=16000x+36000
at 12 years, x=12
y=16000(x)+36000
y=16000(12)+36000
y=192000+36000
y=228000
sales at year 12 is $228,000

Answer:
(9n +10^(-n) -1)/27
Step-by-step explanation:
The tricky part is figuring out how to describe the series. The general term can be described by ...
an = (1/3)(1 -10^(-n))
Then the sum of n terms is ...
Kito makes on online purchase of a guitar case for $39.99, a tuner for $24.99 and picks for $26.99. Taxes are 6% of the total purchase price. Shipping is $8.20-add up the total: 39.99+ 24.99+ 26.99= 91.97 -calculate the sales tax: 91.97 x 0.06= 5.5182 -add in the sales tax: 5.5182+ 91.97= 97.4882 -add in the shipping cost: 97.4882+ 8.20= 105.6882
And you get $105.69 which is option A. Kito has been billed correctly
