Question

One angle of a right angle is 30°. Write the other two angles of the triangles.​

Answer 1

Answer:

60°

Explanation:

Given Angle = 30°

Right angle =90°

Total angle sum of a triangle=180°

Unknown angle = 180°-(90°+30°)

=180°-120°

=60°

Answer 2

Answer:

one angle is 60 & second one is 90

Explanation:

180 = angle a + angle b + angle c

180 = 30 + b + c

180 = 30 + 90(right anglel) + c

180 = 120+c

c=180-120

angle c = 60
