Question

In the figure where 3x+20 and 4x-36, which value of x will make aob, a straight line

Answer 1

Step-by-step explanation:

<xoz+<yoz=180(liner pair)

(3x+20)° +(4x-36)°=180

3x+20+4x-36=180

7x-16=180

7x=180+16

7x=196

x=196\7

x=28 ans

Answer 2

Given: The figure.

To find: Which value of x will make aob a straight line.

Solution:

In order for AOB to be a straight line, the terms must sum up to give 180°. This is because when an angle measure 180°, it forms a straight line.

$3x+20+4x-36=180$

The above equation must be rearranged and the term x must be isolated in order to find its value.

$7x = 196$

$x= 28$

This means that if x is substituted as 28 in the given angles, the line AOB would form a straight line.

Therefore, the value 28 will make aob a straight line.
