Please x

a = 3.46 , c = 9.9

Step-by-step explanation:

These are the following identities:

Easier way to learn this is

Some people have curly brown hair till painted black

Sinx   = per/hyp      cosx  = base/hyp  tanx = per/base

So if use the angle 60° we can see that the opposite side(perpendicular) to the angle is 6 and the base side is a so we need the identity which uses the opposite side(perpendicular side) and the base side and not the hypotenuse so that is tan x so,

So a = 3.46

Now to calculate c:

If we take the angle 45° and see the opposite side(perpendicular side) is 7 and the hypotenuse is c so need the identity which uses the opposite side(perpendicular side) and the hypotenuse and not the base, which is sin x so,

so c = 9.9
