Question

Two angles of a triangle measure 90 Degree and 30 Degree. The measure of the third angle is ------ * 1 point

Answer 1

Answer:

60°

Step-by-step explanation:

Three angles of a triangle constitutes to a sum of 180.

From the given information , we have measures of 2 angles i.e , 30° & 90°

Taking third angle as x , we'll have eqn,

30+90+x = 180

120+x = 180

x = 180-120

= 60°

Answer 2

Answer:

60 degree

Step-by-step explanation:

let third angle be x

90°+30°+x=180° [angle sum property]

120°+x=180°

x=180°-120°

x=60°
