Question

hola me pueden ayudar porfavor ​

Answer 1

Explicación paso a paso:

3.

C + S = 240

(90 - x) + (180 - x) = 240

270 - 2*x = 240

270 - 240 = 2*x

30 = 2*x

15 = x

4.

(3/2)*C = S - C

(3/2)*(90 - x) = 180 - (90 - x)

(3/2)*(90 - x) + (90 - x) = 180

(5/2)*(90 - x ) = 180

90 - x = 180*(2/5)

90 - x = 72

90 - 72 = x

18 = x
