If sin x=-√2/2 and cos x=√2/2 the measure of angle x is

Step-by-step explanation:

We have,

Applying on both sides of equation (i) we get :

We know that,

So,

Also,

So,

Similarly,

Applying on both sides of equation (ii) we get :

We know that,

The cosine function is positive in the first and fourth quadrant.

So,

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

the answer is b.)
