Answer: 90

Step-by-step explanation: mAB =180° as it is a straight angle

x=180-120= 60°

so,The number should be less than 180 but more than 60, be divisible by 30 and be a 2 digit no.

nos. divisible by 30 between 60 and 180 are 90,120 and 150

But there is only one of these that are 2 digit i. e. 90

Therefore, the no. is 90

This is because it’s less than 120°
It’s greater than the degree between c and b which is x
It can be divided by 30, 9 decided by 3 for example
It’s a two digit number
