The value of x when y = 2 is x = 36
Step-by-step explanation:
The equation that we have in this problem is:
In order to find the value of x when y is equal to
y = 2
We need to re-arrange the equation making x the subject.
We proceed as follows:
1) We add +7 on both sides:
2) Now we multiply both sides by 4:
3) Now we can substitute y = 2 and find the value of x:

Answer:
Step-by-step explanation:
a)
the sum of all angles in a quadrilateral must be 360º
y+88+25+35 = 360
y = 360=88-25-35
y = 212º
b)
the sum of all angles in an octagon must be 1080º
45+45+140+140+6y = 1080
6y = 1080-90-280
6y = 710
y = 710/6
y=~ 118,3º
X-8+y^2=52 is the answer I believe
