a. QRM and QLM

b. i. Use Pythagorus theorem which states that c^2=a^2+b^2
c^2=5^2+7^2
c=8,6
RS=8,61

ii. Use trigonometry(Soh Cah Toa)
sin(50)=5/?
PQ=6,52

iii. a^2=6,52^2-5^2
a=4,18
PL=4,18
PS=4,18+4+7=15,18
PS=15,18

iv. Use the i then Sine rule
c ^2=5 ^2+7 ^2
RS=8,61
sin90/8,61=sinx/5
x=35.5
MSR=35.2
