Answer:

B. -√13/4

Step-by-step explanation:

cos 0 = -√3/4 => x=-√3 , h=4

tan 0 > 0

y should be on quadrant III

y= √4²-3= √16-3=√13 => -√13

so, sin 0 = y/h = -√13/4

Groks mother weighed

shusha [124]

Answer:

62 Kg

Step-by-step explanation:

Let g = weight of Grok last year in kg

m = weight of Grok's mother last year in kg

m = 3g

m-4 = 2(g+9)

since m = 3g

(3g)-4 = 2(g+9)

3g -4 = 2g + 18

3g-2g = 18+4

g = 22

m = 3*22

= 66

Note that:

g+9 = weight of Grok now

m-4 = weight of Grok's mother now

Grok weighs 31 Kg now

Grok's mother weighs 62 Kg now
