(4x-13)°+15°+(x+18)°=180
4x-13+15+x+18=180
5x+20=180
5x=180-20
x=32
A=(4x-13)°
=(4×32-13)°
=115°
C=x+18°
=32+18°
=50°
HOPE IT HELPS UH!!☺️☺️
23-y=8 x=16
24-y=1.5 x=1.5
25-b=9 a=8
26-y=3.5 x= 3.5
that's what I know i don't think my answers are fully right
If you divide you get 0.2201
Which is approximately 0.22
Have you tried drawing it out and grouping them like that? it helps to make the dots then draw boxes around it to figure out the problem ( ovo)/)
