Answer:
a =64 °and b = 52°
Step-by-step explanation:
as 360° is the sum of all the internal angles.
As we have 4 a's and 2 b's.(see attachment for the figure).
We write the equation:
4 a + 2b = 360 ---> eq(1)
We are given that the largest angle of the parallelogram is 116º.
So a + b = 116
a= 116-b ---> eq(2)
substituting the above value in eq(1)
(1) => 4( 116-b) + 2b = 360
464 - 4b + 2b = 360
-2b = 360- 464
-2b = -104
b=52
plugging the value of b in eq (2)
(2)=>
a= 116- 52
a= 64
Thus, the values of a is 64 °and b is 52°

(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16
+ 4 + 4
4y = 20
/4 /4
y = 5
(x,y) -> (-4,5)
Hope this helps!
