Question

If 4xº, (5x-15)° and (2x+30)'
are the angles of a triangles
then x= ..................?*​

Answer 1

Answer:

4x+5x-15+2x+30 = 180 °

11x+15= 180°

11x =165

x = 165/11

x = 15

Answer 2

Step-by-step explanation:

Answer :

..........................

4x+5x-15+2x+30=180

11x+15=180

11x=180-15

11x=165

x=165/11=15

4x=4(15)=60 degree

5x-15=5(15)-15=75-15=60degree

2x+30=2(15)+30=30+30=60 degree
