Question

Define angle c if traingle abc,angle b=90 and angle a=30

Answer 1

Answer:

Step-by-step explanation:

60 degrees is the measure of angle c

Answer 2

Answer:

∠c = 60°

Step-by-step explanation:

We know that sum of all angles of a triangle is 180°

Therefore ∠a + ∠b + ∠c = 180°

Substitute the values and you get

30 + 90 + ∠c = 180

∠c = 180 - 120

Therefore ∠c = 60°
