Step-by-step explanation:
if mK is 90 then mD is 60 and mS is 30. since the new point is in the middle of the triangle divide 60 and 30 by 2. Now mD is 30 and Ms is 15 so 30+15=45 so 180-45=135

x=0.15
Step-by-step explanation:
5x+0.25=7x-0.05
5x+0.25-0.25=7x-0.05-0.25
5x=7x-0.3
5x-7x=7x-0.3-7x
-2x=-0.3
-2x/-2 = -0.3/-2
X=0.15
Hope this helps!
