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>
1st dot (0,48) then each dot after than subtract 6 from the Y and add 1 to the x
2nd dot (1,42)
3rd dot (2,36)
etc.

Answer:
J'(5, 5), K'(3, 2), L'(4, 2)
Step-by-step explanation:
Each individual coordinate value is multiplied by the scale factor.
(x, y) ⇒ (x/5, y/5)
J(25, 25) ⇒ J'(5, 5)
K(15, 10) ⇒ K'(3, 2)
L(20, 10) ⇒ L'(4, 2)
1*60 | 60-1 =59
2*30 | 30-2 =28
3*20 | 20+3 = 23
4*15 | 15+4 =19
5*12 | 12+5 =17
6*10 | 10+6 =16
Not possible. You can get a 23. But not 22.
