Question

answer for 3 Rd problem fast​

Answer 1

Answer:

x=30

Step-by-step explanation:

$(2x + 30) + 3x = 180$

[Linear Pair]

$(2x + 30) + 3x = 180 \\ = > 2x + 30 + 3x = 180 \\ = > 5x = 180 - 30 \\ = > x = \frac{150}{5} \\ \\ = >x = 30$

Answer 2

Answer:

x = 30

Step-by-step explanation:

By linear pair= AOB - 180

$then \: x \: value \: be \: = \\ 180 = 2x + 30 + 3x \\ 180 = 5x + 30 \\ 180 - 30 = 5x \\ 150 = 5x \\ x = 150 \div 5 = \\ x = 30$
