Answer:

57⁰

Step-by-step explanation:

A triangle measures 180⁰, so to find the answer to these questions you just have to add the degrees you know

92⁰+31⁰=123⁰

after you take 180⁰ and subtract the degrees you know your triangle has

180⁰-123⁰= 57⁰

Answer:

57°

Step-by-step explanation:

so triangle angles all add up to 180 so its a matter of subtraction

[tex]92 + 31 + x = 180[/tex]

x is the 3rd angle we need to find

[tex]92 + 31 + x = 180\\\\92 + 31 = 123\\\\180 - 123 = 57\\[/tex]

so the missing 3rd angle is 57°
