Answer:

   4. 132°

   5. 41°

Step-by-step explanation:

Q4

  • The arc length is twice the measure of the inscribed angle
  • ∡RP = 68° × 2 = 132°

Q5

  • 2∠ABC = ∡AC
  • 2(5x + 11) = 16x - 26
  • 10x + 22 = 16x - 26
  • 16x - 10x = 22 + 26
  • 6x = 48
  • x = 6
  • ∠ABC = 5(6) + 11
  • ∠ABC = 41°

mRP

The angle will be twice the m<Q

So

it's

  • 2(68)
  • 136°

#2

  • 2(5x+11)=16x-26
  • 10x+22=16x-26
  • 48=6x
  • x=8

m<ABC

  • 5(8)+11
  • 40+11
  • 51
