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

The unknown angles are equal as they are bisected

  • 3a+20=2a+26
  • 3a-2a=26-20
  • a=6
