Question

If the angle of a triangle are 2 a, a + 20 and a + 24 the value of a is what

Answer 1

Answer:

11

Explanation:

2a + a + 20 + a + 24 are the angles of the triangle So,2a + a + a = 24+20 (these are the two equations, marked as 1 and 2)

therefore, 4a =44

a = 44/4=11

11 is the answer

Answer 2

Answer:

Explanation:

Sum of the triangle is 180

2a+a+20+a+24 =180

4a+44 =180

4a=180-44

4a =136

a =136/4

a =34
