can someone help me? I have to turn in these assignments before 12 tonight and i have alot more stuff to do. ILL GIVE A MEDAL AND BECOME A FAN!

Answer 1

One method you can use to determine whether a triangle is a right triangle, given three side lengths, is to apply the Converse of the Pythagorean Theorem. Alternately, you can use trigonometric ratios. Show that the triangle in the diagram is a right triangle by using trigonometric ratios.

Answer 2

Answer 3

if you can show that a^2 + b^2 = c^2 is true, where c is the longest side, then you will have shown that the triangle is a right triangle

Answer 4

a^2 + b^2 = c^2

16^2 + 63^2 = 65^2

256 +3969 = 4225

4225 = 4225

so because the last equation is true, this means the first equation is true

since a^2 + b^2 = c^2 is true when a = 16, b = 63 and c = 65, this means that the triangle is a right triangle

Answer 5

You didn't have to give me the answer lol Leading me through it would have been helpful to but thank you so much! @jim_thompson5910

Answer 6

oh sry about that

Answer 7

hopefully everything makes sense though?

Answer 8

That's okay haha and yes it does i Had no clue how to do this what so ever.

Answer 9

Answer 12

I gotcha

Answer 13

Could you help me with one more?

Answer 14

sure

Answer 15

A surveyor is “shooting a line” to a point on a tree 55 m from his current position. After rotating his surveying instrument 25° to the left, he “shoots” another line to a point on a fence post 25 m away.
a.) Determine the distance between the point on the tree to the point on the fence post. (Show the appropriate formula, substitutions, and work. Give the distance to the nearest hundredth of a meter.)
b.) Use the Law of Sines to find the measure of T. (Show the appropriate formula, substitutions, and work. Give the measure of T to the nearest degree.)
c.) Find the mF.

Answer 16

for part a), you need to use the law of cosines

c^2 = a^2 + b^2 - 2ab*cos(C)

c^2 = 25^2+55^2 - 2*25*55*cos(25)

keep going to solve for c

Answer 17

make sure you're in degree mode on your calculator
