This is the concept of geometry, given that AB=AC, it means that the tirangle is isosceles, thus to get the value of AB and AC we proceed as follows;
thus using the cosine rule:
c^2=a^2+b^2-2abcosC
suppose\AB=AC=x
thus;
8^2=x^2+x^2-2*x*xcos15
64=2x^2-2x^2cos15
64=2x^2-1.9x^2
64=0.1x^2
x^2=640
x=sqrt640
x=25.3
hence;
AC=AB=25.3
Answer:
is the 5.2% per hour or for the whole 25 hours?
Need to know in order to solve the question
Step-by-step explanation:
D because 144 /45% is 320 EZ hope i helped you drop a brianlest for me to pls
Best choice for variables.....I would let students be " s " and parents be " p "
