1.	Calculate the angles of the triangle, if they are in the ratio2:3:4.
Answer» Answer: ✮We know that: The sum of the INTERIOR angle is 180° ✮Solution: Let the UNKNOWN angles be 2x,3x and 4x According to the condition: 2x+3x+4x = 180 ↦ 9X = 180 ↦ x = 180/9 ↦ x = 20 Therefore, The value of x is 20. Now, The FIRST angle is 2x = 2×20 = 40° The SECOND angle is 3x = 3×20 = 60° The third angle is 4x = 4×20 =80° $\:$

✮We know that:

The sum of the INTERIOR angle is 180°

✮Solution:

Let the UNKNOWN angles be 2x,3x and 4x

According to the condition:

2x+3x+4x = 180

↦ 9X = 180

↦ x = 180/9

↦ x = 20

Therefore, The value of x is 20.

Now, The FIRST angle is 2x = 2×20 = 40°

The SECOND angle is 3x = 3×20 = 60°

The third angle is 4x = 4×20 =80°
