Respuesta :
60, 30, and 90 degrees.
180 - 120 = 60
180 - 150 = 30
Since a triangle is 180 degrees, and we already know 2 of them are 60 and 30 degrees, the last one would be 90 degrees.
180 - 120 = 60
180 - 150 = 30
Since a triangle is 180 degrees, and we already know 2 of them are 60 and 30 degrees, the last one would be 90 degrees.
Three interior angles of the given triangle are 60°, 30°, and 90°.
What is a triangle?
A triangle is a two-dimensional geometrical figure that has three sides, three vertices, and three interior angles.
Given, two exterior angles of a triangle are 120° and 150°.
Therefore, the first interior angle is
[tex]= (180 - 120)[/tex] degrees
[tex]= 60[/tex] degrees
The second interior angle is
[tex]= (180 - 150)[/tex] degrees
[tex]= 30[/tex] degrees
The third interior angle is
[tex]= [180 - (60+30)][/tex] degrees
= 90 degrees
