Answer:
a.
b.
Step-by-step explanation:
a. We know that angles in a triangle add up to 180°.
-The right angle triangle in the right triangle has a measure of 90°.
We can therefore equate our angles to 180° and solve for x;
Hence, the angle measure is x=10°
b. Having calculated the value of x from a above as x=10°, we can substitute to find the measures of the two acute angles:
Since, the m∠K is a right angle, it measures 90°
The point-slope form: 
m = -1; (2; 4)
subtitute
y - 2 = -1(x - 4)
m = -1; (2; 4)
subtitute
y - 2 = -1(x - 4)
