Question
Download Solution PDFIn a right-angled triangle PQR, right-angled at Q, the length of the side PR is 17 units, length of the base QR is 8 units, and length of the side PQ is 15 units. If ∠RPQ = α, then sin α + cos α is:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFGiven:
PR = 17
QR = 8
PQ = 15
Concept used:
Sinθ = P/H
Cosθ = B/H
Here,
P = Perpendicular
B = Base
H = Hypotenuse
Calculation:
sin α + cos α
⇒ 8/17 + 15/17
⇒ (8 + 15)/17
⇒ 23/17
∴ The required answer is \(\frac{23}{17}\).
