Answer 1

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

Explanation:

Using trigonometric ratio cos.

Here,

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

Finding x:

`\displaystyle cos \theta =(adjacent)/(hypotenuse) \\\\cos \ x =(12)/(28) \\\\cos \ x = 0.43\\\\x = cos^(-1) 0.43\\\\x = 65 \textdegree\\\\\rule[225]{225}{2}`
