First thing to note, QR + RS = QS
#1, RS = 44.6 and SQ = 68.4
Plug in to the equation I wrote above
QR + 44.6 = 68.4
QR = 23.8
#2, RS = 33.5 and RQ = 80
QR + 33.5 = 80
QR = 46.5
Steps to solve:
15 = x + 13
~Subtract 13 to both sides
2 = x
Best of Luck!
Answer:
2.4
Step-by-step explanation:
Angles of the parallelogram which is given in the problem are:α = 49° + 17 °= 66°
β = 180° - 66° = 114°
x - length of the longest side of the parallelogram;
Use the Sine Law:x / sin 49° = 20/ sin 17°
x / 0.7547 = 20 / 0.2924
0.2924 x = 15.094
x = 15.094 : .2924
x = 51.62 is the longest side of the parallelogram.
