Answer:

Explanation:

Sum of 3 angles of a triangle= 180

3x-2+x+11+4x+3= 180

Separate x terms from constants

3x+x+4x-2+11+3= 180

8x+12= 180

8x= 180-12

8x= 168

x= 168/8

x= 21

Put the value of x in angles:

3x-2=3(21)-2= 63-2= 61

x+11= 21+11= 32

4x+3= 4(21)+3= 84+3= 87

If you want to check whether your answer is right or wrong, you can cross-check by adding the 3 angles

61+32+87= 180.

Hope this will help :)
