We want to find the measure of each .
To do this, we will first find the value of
by using the . This theorem tells us that the measures of the of a triangle add to
Let's create an equation applying this theorem. Be aware that one of the angles is marked as a , and therefore it measures
We will now solve the equation for
Now that we know the value of
we can substitute
into the given expressions to find the measures of the acute angles.
