I NEED HELP!!!!

The map connects cities X, Y, and Z. The highways connecting the cities make a right triangle.



Leo drove from city Y to city Z and Samantha drove from city Y to city X and then from city X to city Z. How many more kilometers did Samantha drive than Leo? Using complete sentences, justify your answer.

Answer 2

thats the explanation?

Answer 3

Yes! the answer and explanation. The question was also on yahoo answers

Answer 4

I dont understand it tho...

Answer 5

1)
(yz)^2=(xy)^2+(xz)^2
(34)^2=(xy)^2+(16)^2

now find xy
and then add
xy+xz+yz
to get ur final answer :)


Look at the figure. If sinx=1/2, what is the value of y?
1/4
3/4
9/4
4/3

answer-
sinx=1/2
sinx=perpendicular/hypotenuse
1/2=9/(8y)
8y=9*2
y=18/8
y=9/4


If sin y=9/c and tan y=9/d, what is the value of cos y?
tany=siny/cosy
9/d = (9/c)/cosy

9/d=9/c*cosy
cosy=9/c*d/9
cosy=d/c

Answer 6

Maybe in simpler terms?

Leo travels Y to X which is 34 km
Sam travels Y to X, which is an unknown length
To find YX you use Pythagorean theorem
16^2 + b^2 = 34^2
YX is equal to 30km now you add 16km( from X to Z) is qual to 46 km
46-34=12 Sam reveled 12 km more than Leo

Second problem the answer is 9/4
Third problem the answer is y=d/c

Answer 7

Thankyou :)
can you help me with another one?

Answer 8

I can try! Maybe you can check out my question too!

Answer 9

Which equation is correct?

sec x° = opposite ÷ adjacent

cot x° = opposite ÷ adjacent

cosec x° = opposite ÷ adjacent

sec x° = hypotenuse ÷ adjacent

Answer 10

the fourth! sec = HYP/ADJ

Answer 11

Look at the figure.



If sin y°= and tan y°= ,what is the value of cos y°?

cos y° = 6/b

cos y ̊= 6a

cos y ̊= 6b

cos y° = b/6

Answer 12

what does sin y equal? what does tan y equal?

Answer 13

sin y= a/6
tan y = a/b

Answer 14

on second

Answer 15

b/6 = cos y

Answer 16

SOH COH TOA

Answer 17

so its d?

Answer 18

i need help with so many questions :/

Answer 19

yes, Its D
