Find the value of x.<br> please help me!!!!!!!!
Zanzabum

Answer:

x = 55° (nearest degree)

Step-by-step explanation:

Trig ratios:

sin(\theta)=\dfrac{O}{H} \ \ \ cos(\theta)=\dfrac{A}{H} \ \ \ tan(\theta)=\dfrac{O}{A} \ \ \

where \theta is the angle, O is the side opposite the angle, A is the side adjacent to the angle, and H is the hypotenuse of a right triangle

Given:

  • \theta=x
  • A = 3.3
  • H = 5.7

\implies cos(x)=\dfrac{3.3}{5.7}

\implies x=\arccos \dfrac{3.3}{5.7}=54.623459...

⇒ x = 55° (nearest degree)
