Cut it in half (the top into a trapezoid and the bottom into another trapdoors then solve both and add them
Answer:
y = 100°
Step-by-step explanation:
I can't see the full question, but I'm guessing you need to find the measure of angle y.
The total angle sum of a polygon can be calculated with the formula
T = 180°(n - 2) where T is the total angle measure, and n i the number of sides.
For our shape, there are 4 sides, so n = 4. Plug that in and simplify...
T = 180°(4 - 2)
T = 180°(2)
T = 360°
We are given 3 of the angles, so angle y is
y = 360 - 107 - 104 - 49
y = 100°
1: Solve for either x or y in one of the equations. So x + y = -1 is y = -x -1
2: substitute the new equation in the opposite equation. So x - (-x - 1) = 7
3: distribute the negative. X + x + 1 = 7
4: combine like terms. 2x + 1 = 7
5: solve for x. Subtract 1 on both sides. 2x = 6
6: divide by 2 to get x by itself. X = 3
7: plug the new value of x into one of the ORIGINAL equations. 3 + y = -1
8: solve for y. Subtract 3 on both sides.
Y = -4
9: the solution is written as (x,y) so the solution would be (3, -4)
Hey there,
So when finding the perimeter, we do addition.
So . . .
20 + 12 + 18 + 7+ 13+6
Your correct answer would be 76
Hope this helps.

Answer:
5 units
Step-by-step explanation:
If you look at AC that has 4 units and DE is close to 4 units but a little bigger by a unit
