Answer:

x=6

Step-by-step explanation:

Since the figure has 4 sides, the total of all of the angles add to 360 as:

180(n-2)=T

180(4-2)=T

180(2)=T

360=T

Now we can set up an equation and solve for x:

17x+8+74+110+66=360

17x+258=360

17x=102

x=6

So x=6

Amnda
X = 6. Since all inside angles of a polynomial add up to be 360 degrees, you can add the three given angles and solve for x. Add the given angles, 74+66+110 = 250. Subtract from 360 to find the fourth angle. 360-250=110. This means 17x+8 = 110. Solve for x by subtracting 8 from both sides, then dividing 17 on both sides to get x = 6.
