A boat sails from point X to point Y and then to point Z. Y is on a bearing of 280° from X. Z is on a bearing of 220° from Y. The distance from X to Y is 3.5 km. The distance from Y to Z is 6 km. Work out the bearing of Z from X. Give your answer correct to 1 decimal place.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
