If the angles of the triangle are 'a + 35, a + 50 and a + 65'. Find the value of 'a'.

Answer 1

Answer:

a+35+a+50+a+65=180

3a+150= 180

3a=30

a=10

Answer 2

Answer:

a = 10

Step-by-step explanation:

a + 35 + a + 50 + a + 65 = 180

• as sum of all angles of triangle is 180

3a + 35 + 50 + 65 = 180

3a + 150 = 180

3a = 180 - 150

3a = 30

a = 30 / 3

a = 10

1. a + 35 = 10 + 35 = 45
2. a + 50 = 10 + 50 = 60
3. a + 65 = 10 + 65 = 75
