Answer:

a = 61

Step-by-step explanation:

The three angles form a straight line which is 180 degrees.

a + 90 + 29 = 180

a + 119 = 180

a = 180-119

a = 61

Given : Find the measure of the missing angle.

Solution : According to the question, here we are provided with a variable α. An angle which is 90° and another angle which is 29° are to be added and the result is 180°. So, subtracting from 180° we will get the required answer

  • α + 90° + 29° = 180° [Reason : straight ∠]

  • α + 119° = 180°

  • α = 180° - 119°

  • α = 61°

Henceforth, the missing angle is 61°
