You have to use the Law of Cosines here, since there's no other way to solve this. it's not a right triangle, so you can't use the Pythagorean Theorem. The Law of Cosines will help us find the missing side length then we will have to use the Law of Sines to find another angle. Then after that we will use the Triangle Angle-Sum theorem to finish it off. Ready? The Law of Cosines to find side b is
and fill in the info we know, which is everything but the b.
. Doing all that math gives us that side b = 40.9 or 41. Now the Law of Sines to find missing angle A or C. Let's find A.
. That gives us that angle A is 29. Now use the fact that all triangles add up to 180 to get that angle C is 42. And you're done!
Answer: 45 dollars and it was a distance of 5 kilometers
Step-by-step explanation: What i did was start with 30, then keep adding 3 till i got the a multiple of 5.
30 + 3 = 33
33 + 3 = 36
36 + 3 = 39
39 + 3 = 42
42 + 3 = 45
So already i know that it is 5 kilometers, because i added 3 to 30 five times.
No i will do that with the second company
20 + 5 = 25
25 + 5 = 30
30 + 5 = 35
35 + 5 = 40
40 + 5 = 45
That is also 5 kilometers, because i added 5 to 20 five times. I also know they are the same price, because they both added to 45 dollars.
Thats how i solved it.
I really hope that helps!
Answer:
no he is not correct because he did not add 234 and 1192 to find the value of h, which is 1426
Step-by-step explanation:
h-234 = 1192
add 234 to each side
h-234+234= 1192+234
h = 1192+234
h = 1426
Angle W and Y are right angles and equal to 90 degrees each. Angle z and angle x are same side interior angles and they have a sum of 180 degrees because of the same side interior angles postulate.
so W= 90 Y=90 X+Z= 180 . so 90+180+90 =360 degrees. B.
