Question

If the angles in a triangle are p + 20, p - 30 and p + 40.
What is the value of p?


With step by step explanation​

Answer 1

Answer:

By condition,

(p+20)+(p-30)+(p+40)=180[As we know sum of all angles of triangles=180°.

3p+30=180

3p=210

p=70°

Answer 2

Answer:

value of p is 50

Step-by-step explanation:

(p + 20) + (p - 30) + (p + 40) = 180 [Angke sum property of a triangle)

=> p + 20 + p - 30 + p + 40 = 180

=> 3p +30 = 180

=> 3p = 180 - 30

=> 3p = 150

=> p = 150 ÷ 3

=> p = 50
