If < A and < B are vertical angles, and < A = 2x - 11 degrees, and < B = x + 7 degrees, find x.

Tema [17]

Answer:

x=18

Step-by-step explanation:

Vertical angles are congruent. This means that they are equal to each other. So, to solve set them equal to each other and isolate x. First, set up the equation. Then, subtract x from both sides. Finally, add 11 to both sides and simplify.

1) $2x-11=x+7$

2) $x-11=7$

3) $x=18$

Schach [20]

Answer:

The solutions are 270° and 450°.

Step-by-step explanation:

Given:

$cos\frac{x}{2} =\frac{\sqrt{2} }{2}$ .

So, the second and third quadrant angle to be calculated.

$cos\frac{x}{2}=135$

$=x=270$ °.

And, $cos\frac{x}{2}=225$

$=x=450$ °

Therefore, the solutions are 270° and 450°.
