Question

ayuda!!! es para mañanaaaaa

Answer 1

Respuesta:

Todos son ángulos rectos (90°)

Explicación paso a paso:

x+ 20 + x = 90

2x = 90 -20

2x = 70

x = 70/2

x = 35

x + 4x - 15 + x = 90

6x - 15 = 90

6x = 90 +15

6x = 105

x= 105/6

x = 17.5

x+ 10 + 2x -5 + x +10= 90

4x + 15 = 90

4x = 90 -15

4x = 75

x = 75/4

x = 18.75

3x + 5x +10= 90

8x = 90 -10

8x = 80

x= 80/8

x= 10

2x + 5 +4x + 25 = 90

6x + 30 = 90

6x = 90 - 30

6x = 60

x = 60/6

x = 10

5x+ 10 +3x = 90

8x = 90 - 10

8x = 80

x = 80/8

x = 10

Listo, éxitos
