Answer:
65
Step-by-step explanation:
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. The principal value of sin⁻¹(1) is 90°.
<h3>What is Sine (Sinθ)?</h3>
The Sine or Sinθ in a right-angle triangle is the ratio of its perpendicular to its Hypotenuse. it is given as,
Sin(θ) = Perpendicular/Hypotenuse
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The hypotenuse is the longest side of the triangle.
The principal value of sin⁻¹(1) is,
θ = Sin⁻¹(1)
θ = 90°
Hence, the principal value of sin⁻¹(1) is 90°.

Answer:
x = (8+y)/3
Step-by-step explanation:
3x-y=8
Add y to each side
3x-y+y=8+y
3x = 8+y
Divide each side by 3
3x/3 = (8+y)/3
x = (8+y)/3
Answer:
153.9
Step-by-step explanation:
Area of a circle formula:
Pi*r*r of Pi*r^2
pi*7*7= Area of circle
pi*49
49* 3.14 is around 153.86 which is around 153.9
