Question

In ∆PQR, if m∠P=x–12,m∠Q=5x–27, and m∠R=2x+3, write an equation and solve for x. x =

Answer 1

Answer:

∠p= 15°  ,  ∠q = 108°   , ∠r = 57°  Is the Answer

Step-by-step explanation:

, (x -12)° + (5x-27)° + (2x + 3)° = 180°

or,  8x° -36° = 180°

Or x =

So, x = 27°

∴ ∠P = 27° -12°  = 15°

 ∠q = (5 × 27)° -27° = 108°

 ∠r = (2 × 27)° + 3° = 57°
