Answer:
<em>D. 57 deg</em>
Step-by-step explanation:
33 + m<MLN + 90 = 180
m<MLN + 33 = 90
m<MLN = 57
m<KLN = m<MLN = 57
First of all
x^2 +10x - 18
use
x = (-b plus or minus (<span>√<span></span></span>(b^2-4ac)))/2a
you will get
(x+5−(<span>√<span><span><span>43)</span></span><span></span></span></span>)(x+5+(<span>√<span><span><span>43</span></span><span>))</span></span></span>
