Answer:

<u>Given</u>

  • 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)

<u>Find QS first</u>

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

<u>Find QT next</u>

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

miv72 [106K]

Answer: 32.52  

Step-by-step explanation :if I’m correct this is supposed to be a decimal ( here we use the dot not the comma ) but if so then 32.52 a good way to remember is 5 or more let it sore (meaning round up) four or less let it rest (meaning it stays the same)
