Question

preciso da letra e, f

Answer 1

e)
(SQ)² = (PQ)*(QR)
(SQ)² = (8)*(18)
(SQ)² = 144
SQ = √144
SQ = 12 cm

(PS)² = (SQ)² + (PQ)²
(PS)² = (12)² + (9)²
(PS)² = 144 + 81
(PS)² = 225
PS = √225
PS = 15 cm


f)
(SR)² = (SQ)² + (QR)²
(SR)² = (12)² + (18)²
(SR)² = 144 + 324
(SR)² = 468
SR = √468
SR = 6√13 cm
