Answer 1

Answer:

$\huge\boxed{\sf x = 65 \textdegree}$

Step-by-step explanation:

Using trigonometric ratio cos.

Here,

• Theta = θ = x
• Adjacent = 12
• Hypotenuse = 28

Finding x:

$\displaystyle cos \theta =\frac{adjacent}{hypotenuse} \\\\cos \ x =\frac{12}{28} \\\\cos \ x = 0.43\\\\x = cos^{-1} 0.43\\\\x = 65 \textdegree\\\\\rule[225]{225}{2}$
