Question

What is the value of s and b? use the picture above and show work please, thank u!

Answer 1

s and b in °

triangle

s-28+b-48+s=180°

2s+b-76=180

2s+b=180+76

2s+b= 256

flat angle

s+b-18=180

s+b= 180+18

s+b= 198

2s+b=256

s+b= 198

per substitution : b = 256-2s

we replace b

s+256-2s=198

-s=198-256

s=58°

calculate b :

s+b=198

58+b=198

b= 198-58=140°
