If the four interior angles of a quadrilateral are, (y+10), (y+5),
(2y-40) and (y-25). what is the value of y.
(y+10) + (y+5) + (2y-40) + (y-25) = 360
5y +10 + 5 - 40 - 25 = 360
Y =
Please tell me
To find the value of y, we can use the fact that the sum of the interior angles of a quadrilateral is always equal to 360 degrees.
So, let's add up the given angles and set the sum equal to 360 degrees:
(y + 10) + (y + 5) + (2y - 40) + (y - 25) = 360
Now, simplify the equation and solve for y:
4y - 50 = 360
Add 50 to both sides to isolate the term with y:
4y = 410
Divide both sides by 4:
y = 410/4
Simplifying the division:
y = 102.5
Therefore, the value of y is 102.5.
