Question

Any chance someone can do these for me Plz lol need them badly

Answer 1

Answer:

(9)2.43m

(10)900ft.

(11)option (D)4800ft.

Step-by-step explanation:

(9)

sin15°=1.58/x

0.65=1.58/x

65/100=158/100x

65x=158

x=158/65

x= 2.43m

x=243/100m

(10)

tan 7°=90/x

tan 7° ~= 0.1=1/10

so, 1/10=90/x

x=90*10

x=900ft. This is the nearest one because diagonal distance is always greater as it is prooved in Pythagoras theorem.

(11)

sin 30°=2400/x

1/2=2400/x

x=2400*2

x= 4800ft.

option (D)

I hope it helped you
