Answer:
28. m<A=20°, m<B=70°
32. m<A=103°, m<B=77°
Step-by-step explanation:
complementary angle=a+b=90°
supplementary angle=a+b=180°
28. A+B=90°
5x+17x+2=90°
22x+2=90°
22x=90-2
22x=88
22x/22=88/22
x=88/22=<u>4</u>
m<A=5x=5*4=<u>20°</u>
m<B=17x+2=17*4+2=68+2=<u>70°</u>
<u>Check</u>
A+B=90°
20+70=90°
<u>90°=90°</u>
32. A+B=180°
x+11+x-15=180°
2x-4=180°
2x=180+4
2x=184
2x/2=184/2
x=184/2
x=<u>92</u>
m<A=x+11=92+11=<u>103°</u>
m<B=x-15=92-15=<u>77°</u>
<u>Check</u>
A+B=180°
103+77=180°
<u>180°=180°</u>

Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50
