Answer:
  
Reason: the sum of all interior angles of any triangle is equal to 180º.
Step-by-step explanation:
1) Organizing 
Statement  1. m∠H = 30°, m∠J = 50°, m∠P = 50°, m∠N = 100° 1. Reason: given 
2) Since the sum of all internal angles of any triangle is equal to 180º, just like the formula. N the number of sides of a triangle:

3) We can also say 

Similarly to the other triangle:

4) Hence, 

Reason: The sum of interior angles is equal to 180º.

Answer:
first find 20 percent of 270
270 times 20 divided by 100
5400 divided by 100
54
270 plus 54
324 is your final answer
