Answer:
a = 6
Step-by-step explanation:
The two triangles shown are congruent to each other bc the markings shown (rt angle, 1 pair of congruent sides), also KM congruent to itself. Triangles congruent by Hypotenuse-Leg.
So the two angles are congruent to each other.
3a + 20 = 2a + 26 SUBTRACT 2a
a + 20 = 26 SUBTRACT 20
a = 6
