Answer 1

Answer:

60°

Step-by-step explanation:

According to angle sum property of a triangle, sum of angles of a triangle is 180°. Since, two of its angles are given,thus the third angle can be given as

Third angle- 180°-(90+30)°=60°.

Answer 2

Answer:

option (iii)60 is the right answer

Let a triangle ABC, such that

∠A=90∘ ,∠B=30∘

Now,

∠A+∠B+∠C=180∘⇒90 +30∘ +∠C=180∘

⇒∠C=180−120

∴∠C=60
