Find y<br> Round to the nearest tenth:<br> 28°<br> X<br> 350 ft<br> y<br> y = [ ? ]ft<br> Enter
NeTakaya

Answer:

y = 658.3 ft

Step-by-step explanation:

Angle of depression = angle of elevation = 28° (alternate angles are congruent)

Reference angle = 28°

Side length opposite to reference angle = 350 ft

Adjacent = y

Apply trigonometric function, TOA:

Tan 28 = Opp/Adj

Tan 28 = 350/y

y*Tan 28 = 350

y = 350/Tan 28

y = 658.254263 ≈ 658.3 ft (nearest tenth)

Calculate the area of each circle
Triss [41]

Answer:

1.54 in²

Step-by-step explanation:

Given that,

→ Radius (r) = 0.7 in

Formula we use,

→ πr²

The area of the circle will be,

→ πr²

→ (22/7) × 0.7 × 0.7

→ (22/7) × 0.49

→ [ 1.54 in² ]

Hence, area of circle is 1.54 in².
