You would do 20-6 which = 14. + 1 =15. times 8= 120 then divide that by 1/2 = 240 if you do 120 divided by .5 in a calculator thats what you get. i hope that helps you
a parallel line has the same gradient, so the gradient would be 3 1/3
a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)
C/sinB = 8/sinC
c/sinB=8/0.64
c/sinB=12.5
c=12.5*0.34
c=4.25
8*8+4.25*4.25=a^2
64+18.06=a^2
82.06=a^2
a=sqrt(82.06
a=9.05
Answer:what lololololololololol
0.0004702 I always learnt to do this by moving the the decimal point across (left in the case of a minus power) as many steps as the power
