Question

In ∆ pqr, PS is perpendicular to QR. If pe= 9 , find length QR.

Answer 1

Answer:

Step-by-step explanation:

Sides: a = 1   b = 1   c = 1

Area: T = 0.433

Perimeter: p = 3

Semiperimeter: s = 1.5

Angle ∠ A = α = 60° = 1.047 rad

Angle ∠ B = β = 60° = 1.047 rad

Angle ∠ C = γ = 60° = 1.047 rad

Height: ha = 0.866

Height: hb = 0.866

Height: hc = 0.866

Median: ma = 0.866

Median: mb = 0.866

Median: mc = 0.866

Answer 2

questions is wrong because pe is not any side of triangle
