Question

answer this with full sum​

Answer 1

Answer:

sum of all sides of triangle=180°

Step-by-step explanation:

180=30+x+90 (because this is a 90°Angle)

180=120+x

x=180°-120°

=60

x=60

Answer 2

Answer:

x = 60°

Step-by-step explanation:

because The sum of the three angles of a triangle is 180

so one of angle is 30°and it is a Right triangle mean the other angle is 90° so

x = 180-(30+90)

x= 180-120

x= 60

so x=60°
