Answer:
x= (y+7)/b
Step-by-step explanation:
y=3bx-7
3bx= y+7
x= (y+7)/3b
The figure has 5 sides, so it must be a pentagon. Pentagon’s interior angles sum up to 540°.
Therefore:
132+90+3x=540
222+3x=540
3x=318
x=106
Checking work, where x=106
222+3(106)=540.
So x°=106°
Yes 0 is the correct answer
To estimate the answer just look at each number so
495 thats approximately 500
812 thats approximately 800
soo 500 + 800 = 1300
It is statistical because there can be a variety of answers.
