Answer:

107.86 to 2 d.p.

Step-by-step explanation:

makes a triangle. 120 feet is the hypotenuse.

we want to find the opposite so we will use sine.

sin(x) = opp/hyp which means opp = sin(x)hyp.

opp = sin(64)120

opp = 107.86 to 2d.p.

Will says that in the number 8,184​, one 8 is 10 times as great as the other 8. Is he ​correct? Explain why or why not.
Vinil7 [7]
No he is not correct .
Break apart the number 8,184
You will get
8000 + 100 + 80 + 4

The numbers we are comparing are 8000 and 80

80 x 10 = 800

The number we are looking for is 8000

This makes the claim that one 8 is 10 times greater false as it is in fact 100 times as great.
