Question

If a right-angled triangle has one angle equal to 30 degrees. Find the third angle.

Answer 1

Step-by-step explanation:

one angle is 90

second angle is 30

so third angle =?

first angle+ second angle+third angle=180

so put values?

We get third angle= 60

Answer 2

solution: let the name of triangle be ABC

angle B= 90⁰ -- ( Right angle)

angle A= 30

find: angle C= ?

so. C=A+B-180

C= 30+90-180

= 120-180

= 60

so. angle C= 60
