Question

The measures of two angles of a triangle are 72° and 58° . Find the measure of the third angle.​

Answer 1

Answer:

Sum of all angles = 180

x +72 + 58 = 180

x +130 = 180

x = 180 - 130

Answer 2

Answer:

sum of all angles

of traingle. = 180⁰

first angle. = 72⁰

second angle.= 58⁰

third angle =

72⁰+58⁰= 80⁰

sum of all angles

of traingle. =. 180⁰

180⁰ -80⁰= 100 ⁰

third angle = 100⁰.
