Question

Can someone help me plz its my last question

Answer 1

You can almost use the sin law:
i.e. Sin(35) /h = Sin(H) /660

Answer 2

you just need to find the H, and then apply the sine law to solve for h.

Answer 3

ok so how would i do that i see it right there

Answer 4

you know that the angle T=90, O=35 and the only unknown angle is H.
There is a rule, that the sum of all angles in a triangle is equal to 180 degrees.

In your case that would mean that T + O + H = 180
you know angles T and O, but not the H, so:
90 + 35 + H = 180
(the find H)

Answer 5

OHHH every triangle equals up to 180 degrees

Answer 6

so what we would do is grab 180 and subtract it and do 180 - 90 - 35=

Answer 7

not "up to" 180 degrees, but EXACTLY 180 degrees.

Answer 8

yes, very nice.
H=180-90-35

Answer 9

55

Answer 10

Yes, that is correct

Answer 11

Now we can use the sine law

Sin(35) /h = Sin(H) /660

plugging in our H,

Sin(35) /h = Sin(55) /660

Answer 12

Sweet so thats it h is 55

Answer 13

no lowercase h is the height.
The angle you need ed and found to be 55 is H, uppercase.

Answer 14

Sin(35) /55 = Sin(55) /660

Answer 15

no, you didn't find h, you only found H.

Answer 16

o i get it

Answer 17

(lowercase H is the angle. you used the rule about the sum of angles in a triangle to obtain H. the h, lowercase, you still need to find.)

Answer 18

yes....

Answer 19

Sin(35) /h = Sin(55) /660

Answer 20

now, use your calculator, and you are done.....

Answer 21

0.819 i got for sin55

Answer 22

1.24 for it divided

Answer 23

Sin(35) /h = Sin(55) /660

samewise,

h / Sin(35) = 660/ Sin(55)

h = 660 * Sin(35) / Sin(55)

Answer 25

(the approximate result, is under "decimal approximation")
