Question

If h = 3cm, AB=50m and QR= 8cm ,Find H​

Answer 1

Given :-

• h = 3 cm.
• AB = 50 cm.
• QR = 8 cm.

To Find :-

• H = ?

Answer :-

in ∆QRP and ∆BAP we have,

→ QR ll AB,

so,

→ ∠PQR = ∠PBA {Alternate angles.}

→ ∠PRQ = ∠PAB {Alternate angles.}

then,

→ ∆QRP ~ ∆BAP (By AA similarity .)

therefore,

→ QR / AB = h / H

→ 8 / 50 = 3 / H

→ 8H = 50 * 3

→ 4H = 75

→ H = 18.75 cm . (Ans.)
