Question

In the figure. if his parallel m and n,l (X+30),
and 2=(2x+15)find 3and 4​​

Answer 1

Step-by-step explanation:

angle1+ angle2= 180° (co-interior property)

x+30+2x+15 = 180°

3x+45=180°

3x=180°-45°

3x=135°

x= 135°÷3

x= 45°

angle1 =(x+30)=45+30=75°

angle2 =(2x+15)=2×45+15= 105°

angle1=angle3( vertically opposite)

angle2=angle4(vertically opposite)

angle3=75°

angle4=105°
