We know the sum of all the angles in a quadilateral is equal to 360. so,
it would be: 360 - (74+93+117)
= 360 - 284
= 76 degrees
So, Your final answer is 76 degrees.
Hope this helps!
AB is 6
BC is 4
CD is 6
DA is 8
A is 45degrees
B is 130dgrees
C is 130degrees
D is 45degrees (about)
Your answer is the third one. WHen it comes to system of equations, this will cancel out 4a, therefore isolating the variable. That turns the equation into -2b=-5.
37/40 but you should probably wait for a second opinion because i bad at math
