Answer 2

Answer:

x+y+z=360°

Step-by-step explanation:

Let the unknown angle in the Triangle be a.

90°+30°+a=180° (Sum of all the angles of the triangle is 180°)

a=180°-120°

a=60°

According to the figure,

• 90°+x=180° (Sum of all angles on a line is 180°)

        x=180°-90°

        x=90°

• z+30°=180° (Sum of all angles on a line is 180°)

       z=180°-30°

       z=150°

• a+y=180° (Sum of all angles on a line is 180°)

       60°+y=180°

       y=180°-60°

       y=120°

To Find:-

x+y+z

Solution:-

x+y+z=90°+120°+150°=360°
