<span>(a.)
Let's say α is the angle that subtends from the top of the screen to horizontal eye-level.
Let β be the angle that subtends from the bottom of the screen to horizontal eye-level.
tanα = (22 + 10 - 4) / x = 28/x
α = arctan(28/x)
tanβ = (10 - 4) / x = 6/x
β = arctan(6/x)
Ɵ = α - β
Ɵ = arctan(28/x) - arctan(6/x)
(b.)
tanƟ = tan(α - β) = (tanα - tanβ) / (1 + tanα tanβ)
tanƟ = (28/x - 6/x) / [1 + (28/x)(6/x)]
tanƟ = (22/x) / [1 + (168/x²)]
tanƟ = 22x / (x² + 168)
Ɵ = arctan[22x / (x² + 168)]</span>
That's basically any number that's larger than 3/4.
4/4
73/6
9/9
11/12
etc.
Answer:
Rs. 1186 is the required answer.
Step by step answer:
Given:
Principle (P)=$1500
Rate of Interest (R)= 6%
Time period (T)=10 years
Compound Interest (CI)=P((1+6/100)^T-1)
=1500((1+6/100)^10-1)
= Rs. 1186 (approximately)
