Really stuck on this A-Level maths Q. Is it even possible?!Watch
Been stuck on this A-Level maths question for a while, starting to wonder if it is even possible to work out!
Any help please???
Take the longer side as "20+x"
And do some simultaneous trigonometry maybe?
So solve the simultaneous trig equations
Tan(46) X (x)= y
And solve for x and y
Anyways here you have two similar cases (two triangles) that are related to each other. The first thing that should come to mind is simultaneous equations - with two unknown variables only so that you can solve them
So try building up two simple simultaneous equation (using sin or tan ratios is the key) - each having two but the same unknown variables - one of which is h, the height. You can start by assigning a variable to the unknown distance from the flag pole in his first position.
