Find y. Round to the nearest tenth.
Please help me!!!

Answer:
y ≈ 358.3 ft
Step-by-step explanation:
The angle in the right side of the triangle = 28° ( alternate angle )
Using the tangent ratio in the right triangle to solve for y
tan28° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{350}{y}[/tex]
Multiply both sides by y
y × tan28° = 350 ( divide both sides by tan28° )
y = [tex]\frac{350}{tan28}[/tex] ≈ 658.3 ft
y = 658.3ft. The value of the side y of the right triangle shown in the image is 658.3ft.
The key to solve this problem we have to use the trigonometric functions tan θ = opposite leg/adjacent leg
To find side y, where opposite leg = 350ft, adjacent leg = y, and θ = 28° by symmetry:
tan θ = opposite leg/adjacent leg
tan 28° = 350ft/y
Clear y:
y = 350ft/tan 28°
y = 658.254ft
Round to the nearest tenths y = 658.3ft
