-A flagpole is supported by three wires BA, BC and BD, as shown in this diagram.
a Calculate ADB.
b Find the area of triangle ABD.
c Find the angle of elevation of the top of the tower from point C.
d Show that triangle ABC is not right angled

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer: c i think

step-by-step explanation:

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
