Looks like you did most of it.

The next step would be setting them equal to 105, like the problem suggests.

5z+3x+7x=105

15x=105

x=7

Then we can plug back in to find the numbers.

5*7=35

3*7=21

7*7=49

35+21+49=105

The three numbers are 35, 21, 49.

Hope this helps.

頑張って!

Answer:

150

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360.  Let x be the unknown angle

30+70+110+x = 360

Combine like terms

210 +x = 360

Subtract 210 from each side

210+x-210 = 360-210

x = 150
