Idk to be honest but someone will definitely help you
The sum of all the angles in a pentagon is 540 degrees.
To solve for x, you must add up all the known angles and then subtract from 540.
So, you. Would do, 540-(100+100+90+120)
That equals 540-510 which is 30.
Your final answer is x=30
Hope it helps!!
