Answer 1

Answer:

(a) x = 60 deg.

(b) x = 70 deg.

Step-by-step explanation:

(a)

We know that,

sum of all angles of triangle = 180 deg.

x + 90 + 30 = 180

x + 120 =  180

x = 180 - 120

x = 60 deg.

(b)

We know that,

sum of all angles of triangle = 180 deg.

x + 50 + 60 = 180

x + 110 =  180

x = 180 - 110

x = 70 deg.
