Step-by-step explanation:

We need to get both of them to a common denominator. The simplest way to do this is just multiply the denominators by each other. this comes out to 135. But what you do to the denominator, you have to do to the numerator. 5(15)/9(15). 4(9)/15(9)

The 5/9 comes out to be 75/135 and the 4/15 comes out to be 36/135. Subtract the Smaller one from the bigger one to find the difference, in this case being 39/135. Then to simplify, we need see if we can find a common factor of 135 and 39, which we do: 3. divide both of them by three, and we get the final answer to come out as 13/45, which is the final answer (we know it cant simplify any further since 13 is a prime number).

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
