So the exterior angle of any polygons are 360 in total. since in the pic there r some interior angles, we need to 180 - interior to get the exterior angle. since they're adjacent angles on a straight line.
so therefore we get
51 + 66 + x + 180 - 132 + 78 + 180 - 139 = 360 (sum of exterior angle of polygon)
284 + x = 360
x = 76°
so it's C.
Hey there!
-1.3n = 7.8
First, you have to DIVIDE both sides by -1.3
-1.3n / -1.3 = 7.8 / -1.3
Cancel out: -1.3 / -1.3 because it gives you the value of 1
Keep: 7.8 / -1.3 because it gives us the value of n
7.8 ÷ -1.3 = -6
Thus, n = -6 ✅
Good luck on your assignment and enjoy your day!

The measure of QS from the given line is 10
<h3>Addition postulate</h3>
From the given diagram below, we will use the following addition postulate;
QR + RS + ST =QT
Given the following parameters
RT = 15
RS = 7 , and
QT = 18
Substitute
QR + RT =QT
QR + 15 = 18
QR = 18 - 15
QR =3
Determine QS
QS = QR + RS
QS = 3 + 7
QS = 10
Hence the measure of QS from the given line is 10
