Answer:

a = 60

b = 60

c = 120

Step-by-step explanation:

For a;

a + 120 = 180

This is because angles on a straight line are supplementary

a = 180-120

a = 60

a = b = 60

This is because they are corresponding angles and corresponding angles are equal

c = 120

This is because they are alternate exterior angles and alternate exterior angles are equal

Answer:

2 \frac{1}{20}

Step-by-step explanation:

for question a)

It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)

to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.

E.g.

7 \frac{1}{4} = 7x4 + 1 = 29

Thus, improper fraction would be \frac{29}{4}

do same thing  for other one

thus , \frac{26}{5}

now,

\frac{29}{4} - \frac{26}{5}

however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)

\frac{145}{20} -\frac{104}{20} = \frac{41}{20}

convert back to mixed number

2 \frac{1}{20}
