Answer:

The desired missing angle is 43⁰.

Step-by-step explanation:

Ans.

=> Let the missing angle be 'x'.

Then,

59⁰+78⁰+'x' = 180⁰ [:: the sum of interior angles of triangle is always 180⁰]

or,137⁰+'x'=180⁰

or 'x' = 180⁰-137⁰[the position 137 is now negative while performing in another equation]

HENCE,'x'=43⁰
