inysia [295]

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>

∆JKL has vertices J(25,25), K (15,10), and L (20,10). What are the vertices of the image after a dilation with a scale factor of
Gwar [14]

9514 1404 393

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)

What 2 numbers multiply to 60 and add up to 22
allochka39001 [22]
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.
