What is does a equal
Blababa [14]

Answer:

<u>a = 13</u>

Step-by-step explanation:

We should know that: The sum of the interior angles of the triangle = 180°

Given the measure of the angles: (6a - 2) , (5a - 13) and (5a - 13)

So,

(6a - 2) + (5a - 13) + (5a - 13) = 180°

16 a - 28= 180               ⇒ Add 28 to both sides

16 a = 180 + 28 = 208  ⇒ Divide both sides by 16

a = 208/16 = 13
