Answer:
Step-by-step explanation:
a). By applying tangent rule in the triangle,
tanθ =
θ =
θ = 36.87°
Therefore, θ < 45°
b). By using cosine rule in this triangle,
cosθ =
cosθ =
θ = 45°
c). By using tangent rule,
tanθ =
θ =
θ = 75.96°
θ > 45°
Answer:
9.9 cm
Step-by-step explanation:
As we can see in the diagram that the total of straight line has 180 degrees
Therefore ∠RPQ is 180 degrees - 123 degrees = 57 degree
And, arc length is equivalent to the circumference of circle i.e
where,
Pie = 22 by 7
Therefore the approximate length of QR is 9.9 cm
We simply applied the above calculation so that we get to know the length and the same is to be considered
X = 6 and -6
