# Write down the measures of

**(a)** some acute angles

**(b)** some obtuse angles

(give at least two examples of each)

**To do:**

We have to write the measures of

(a) some acute angles

(b) some obtuse angles

**Solutions:**

(a) An acute angle is an angle less than $90^o$.

Therefore, the measures of some acute angles are $89^o, 43^o$.

(b) An obtuse angle is an angle greater than $90^o$.

Therefore, the measures of some obtuse angles are $91^o, 137^o$.
