Looks like the system is

We can eliminate by taking

so that , and

Substitute into this last equation and solve for :

Then

Plug these values into any one of the original equation to solve for :

Hence the solution is x = 4, y = -3, and z = 2.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
