Question

Given 2 ||

Answer 1

Answer:

x = 10

Step-by-step explanation:

Given,

l || m

Therefore,

142° + (3x+8)° = 180° [Since Co-exterior angles]

=> 3x + 8 = 180 - 142

=> 3x + 8 = 38

=> 3x = 38 - 8

=> 3x = 30

$= > x = \frac{30}{3}$

=> x = 10 (Ans)

Answer 2

Answer: x = 8°

Step-by-step explanation:

The angle corresponding to 148° = 148° (Corresponding angles)

148 + 3x + 8 = 180 (Linear Pair)

156 + 3x = 180

3x = 180 - 156

3x = 24

x = 24/3

x = 8

Therefore x = 8°
