Answer:

Given

  • ΔTQR is right
  • QS is altitude
  • ΔRSQ and ΔTSQ also right
  • m∠TQS = 42°, RS = 26 cm

∠RQS and ∠TQS are complementary with ∠TQS, so are 48°

a)

  • ∠QRS is the another one with 42°

b)

Find QS first

  • 26/QS = tan 48°
  • QS = 26 / tan 48° = 23.4

Find QT next

  • QS/QT = cos 42°
  • QT = QS / cos 42° = 23.4 / cos 42° = 31.5 (rounded)
