You need to work out the other angles first, before working out the values of; a, b and c.
∠x = 180 - 139   [∠'s on a straight line]
thus, ∠x = 41°
∠y = ∠x    [corresponding angles]
∴ ∠y = 41°

∠h = 180 - (41 + 77 + 36)    [∠'s on a straight line add to 180°]
∠h = 26°

∠p = ∠h + 77° +∠y    [corresponding ∠'s]
∴ ∠p = 26 + 77 + 41
   ∠p = 144°

∠a = 180 - (26 + 77 + 41)    [∠'s on a straight line]
∠a = 180 - 144
thus, ∠a = 36°

∠c = 36 + ∠h     [corresponding ∠'s]
 ∠c = 36 + 26
∴ ∠c = 62°

∠b = 180 - ∠c     [∠'s in a straight line add to 180°]
∠b = 180 - 62 
thus, ∠b = 118°

Hope you followed through. :)

31.693 Rounded to the nearest Hundredth ​
ioda

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

31.69

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • '9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
  • Since 3 is less than or equal to 4, we would round down.

⸻⸻⸻⸻

31.693 ≈ 31.69

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
