Heya ☺

Given that

First angle = (30 - a)°

Second angle = (125 + 2a)°

Solution

We know that if the sum of the measures of two angles is equal to 180° , then it is a supplementary angle.

according to question,

(30 - a) + (125 + 2a) = 180

=> 30 - a + 125 + 2a = 180

=> 155 + a = 180

=> a = 180 - 155

=> a = 25

Hence , first angle = (30 -25)° = 5°

second angle = (125 + 2 × 25)°

= (125 + 50)°

= 175°




Thanks

Since, (30-a) and (125+2a) are supplementary angles,
            30-a+125+2a = 180
              a+155 = 180
               a = 180-155
                  = 25
 
      Hence, the value of "a" = 25
