Question

If 127° and 23° are measures of two angles of a triangle, what is the measure of the third angle?

Answer 1

Answer:

30 degrees

Step-by-step explanation:

127 degree + 23 degree + x degree = 180 degree

x degree =[180 - 127 - 23 ] degrees

x = 30 degrees

third angle measure is 30 degrees

Answer 2

..QUESTION..

If 127⁰ and 23⁰ are the measures of two angles of a triangle , what is the measure of the third angle ?

..ANSWER..

Given here ,

ㅤㅤㅤ➪ 1st angle = 127⁰

ㅤㅤㅤ➪ 2nd angle = 23⁰

★ Let the third angle be ' x '

ㅤㅤㅤ

•°• We Know That ,

➪ sum of interior angles of ∆ = 180⁰

•°• According the Question

➪ 1st angle+2nd angle+3rd angle = 180⁰

ㅤㅤ➪ 127⁰ + 23⁰ + x = 180⁰

ㅤㅤ➪ 23⁰ + x = 180⁰ - 127⁰

ㅤㅤ➪ x = 53⁰ - 23⁰

ㅤㅤ➪ x = 30⁰

•°• The third angle is 30⁰

Verification of the answer :

ㅤㅤㅤ♧︎︎︎ L.H.S

➪ 127⁰ + 23⁰ + x

➪ 127⁰ + 23⁰ + 30⁰

➪ 150⁰ + 30⁰

➪ 180⁰ = R.H.S
