Question

1) With the information given in the
adjoining figure and line l
Il line m find the value of y.

​

Answer 1

Answer:

X&Y in linear of pair .The value of X = Y

Answer 2

Answer:

y = 144°

Step-by-step explanation:

l ║ m and "n" is transversal ===> y = 4x (alternate exterior angles)

y + x = 180° (supplementary angles) ===> y = 180° - x

4x = 180° - x

5x = 180°

x = 36°

y = 4 × 36° = 144°
