3/4 of 1/3 =? please show me how to do it
inysia [295]
I haven’t done this in a while, but I believe that the “of” in the equation means multiply so you do 3/4 x 1/3 to get 3/12 (simplified to 1/4)!!

PLLLZZZ HELP ME !!!! WILL GIVE BRAINLIESTTT!!!
sdas [7]

The interior angles of a 7 sided figure add up to 900o That's because if you pick any vertex of an angle and draw diameters so that you create triangles, you will get 5 triangles. In general the interior angles will add up to (n - 2)*180 where n is the number of sides of a polygon.

So the simple way to do this is to equate the seven angles + x to 900

Equation

x + 125 + 126 + 158 + 120 + 139 + 121 = 900

Solve

x + 789 = 900  Subtract 789 from both sides.

x = 900 - 789

x = 111  <<<<< answer
