We know that a = b and c = 30

Since b + 30 = 90, we know b = 60.
That means a = 60

a = 60
b = 60
c = 30

Answer:

a) 60°

b) 60°

c) 30°

Step-by-step explanation:

Get 60 by subtracting 30 from 90 because the angle is a right angle. Since b is identical to a and also is a right triangle, it will also be 60. Get c as 30 by looking at its vertical angle across from it.

Airline companies raise and lower their ticket prices based on the supply and demand. Due to high numbers of fliers, one company
vovikov84 [41]
The raised price represents 110% of the original price (100% plus the extra 10%)

A percentage is converted into a decimal multiplier by dividing by 100:
\frac{110}{100}  = 1.10

To clarify the final stage, consider this (where n is the original price):
n * 1.10 = 192.50
1.10n = 192.50

From here, basic algebraic rules make solving for n easy:
n =  \frac{192.50}{1.10} = 175

Therefore the original price of a ticket was $175
