Question

pfv gente me ajuda :(((((((​

Answer 1

5) a

6) d

7) b

5) 3x+24+4x-18 = 90°

3x+4x = 90-24+18

7x = 84

x = 84/7

x = 12°

6) 9x+8+4x+3 = 180°

9x+4x = 180-8-3

13x = 169

x = 169/13

x = 13°

7) 5x-24+3x+14+7x-5 = 360°

5x+3x+7x = 360+24-14+5

15x = 375

x = 375/15

x = 25

Achando o menor ângulo

3x+14

3(25)+14

75+14

89
