Answer:
a = 180° -73°
b = 73°
c = 180° -73°
Step-by-step explanation:
73° and b are vertical angles, so are congruent (equal).
a and c are equal to each other and each is a linear angle with 73°, so is the supplement of that angle. You could write the equation as ...
a + 73° = 180°
but I prefer to get to the heart of it. The values of a and c are the difference between 180° and 73°.
Answer:
2/3
Step-by-step explanation:
Answer:
first get a common denominator by multiplying 7 and 4 to get 28
28 is our common denominator here.
Step-by-step explanation:
We want to add the fractions 2/7 and 1/4
(2/7) * (4/4) and (1/4) * (7/7)
(2/7) * (4/4) + (1/4) * (7/7) = 8/28 + 7/28 = 15/28
There are many different ratios that are equivalent to 1:6. The way to get an equivalent ratio is to multiple the same integer by the numerator and denominator. So if you multiplied the top and bottom by 2, the ratio would not be 2:12, which is equivalent to 1:6.
