I need to know how many miles the race is
First, add 2 to both sides. You should have 3/2x=21. Multiply both sides by 2 which gives you 3x= 42. Divide by 3 and you have x=14
It is the last choice, 12
seven times two is 14
74-14=60
60/5=12
Hope this helps!!
Use the Cosine Rule to find this
cos <B = [b^2 - a^2 - c^2] / -2ac
= [ 4^2 - 10^2 - 11^2] / -2*10*11
= 0.93182
so m < B = 21.3 degrees to nearest tenth. Answer
Mm im not 100% sure but im pretty sure if you take 10 + 28 and get 38 and then 760 - 38 should be the answer
Soo i think the answer should be 722 meters or whatever
