ANSWER
The value of theta in the second quadrant is,

EXPLANATION
The given trigonometric equation is

This implies that,

This implies that the principal solution is

and it is an angle in the first quadrant.
But the solution we are looking for is an angle in the second quadrant.
This is given by
Answer:

Step-by-step explanation:
If a, b, c are three sides of the triangle, then

In your case, two sides have measures of 4 units and 8 units, then

Hence,

Therefore,

Well you have to do PEMDAS
So we have an exponent so that will turn into a positive X
X+4x=10
So now we combine our X's together to get 5X=10
Now we divide both sides by X which gives us 2
