Answer:
3x = 77.75 9x = 233.25
Step-by-step explanation:
all of the angled inside the quadrilaterals need to add up to 360º
I am assuming the 1 on the top is an angle... it is missing a degrees sign
1 + 3x + 9x + 48 = 360
1 + 12x = 312
12x = 311
x = 25.916
plug x into the angles to find them...
You can double check if this is correct by adding them all together at the end and see if it equals 360
Hope this helps!!
