Answer:

B= 133° C= 47°

Step-by-step explanation:

As shows on the right it's 133°

A= 133°

c+a =180° -a

= 180° -133°

=47°

a and c complement each other and

b= a = 133°

a and b are vertical angles

Answer:

$x=8$

Step-by-step explanation:

The best way to go about this is to use a trig identity. You have the unknown opposite the angle and the hypotenuse, so its best to use the sine identity: $sin(x)=\frac{O}{H}$ , where O is the opposite side, and H is the hypotenuse.

Set up the equation as: $sin(27)=\frac{x}{17}$ , and solve for X.

I got x=7.718, rounded to x=8.

If I helped, a brainliest answer would be greatly appreciated!
