# Acute triangle

In the acute triangle KLM, V is the intersection of its heights and X is the heel of height to the side KL. The axis of the angle XVL is parallel to the side LM and the angle MKL is 70°. What size are the KLM and KML angles?

KLM =  55 °
KML =  55 °

### Step-by-step explanation:

$KML=180-MKL-KLM=180-70-55=55\text{°}$
