Question

Please help me doing this Find X , y and z​

Answer 1

Step-by-step explanation:

Sum of all angles of a triangle = 180°

=> x + 100° + 30° = 180°

=> x = 180° - 130° = 50°

y = 180° - 100° (Because they form a pair of supplementary angles as they lie on a straight line).

=>y= 80°

Similarly,

z + y + 30° = 180°

=> z = 180° - 30° - y = 180° -30° - 80° = 70°
