Question

I urgently have to make study geometry flashcards and i need help with them please Mainly about shapes Please i have my EOC on thursday

Answer 1

What can i say about this triangle?

Answer 2

@mathstudent55 @Luigi0210 @SithsAndGiggles please

Answer 3

@jim_thompson5910 sorry for bothering you plz

Answer 4

@iPwnBunnies are you good with this? or its too geometry for you

Answer 5

This is the easiest question you've asked so far lol. Solve for x?

Answer 6

what do all the sides together have to equal?

Answer 7

No, it's the sum of the interior angles of a triangle.
Don't you know the sum of the angles in a triangle is always 180 degrees?
Can you solve for x now?

Answer 8

Sorry i meant angles cuz obv sides cant do anything here lol and i didnt know if Alwayss

Answer 9

Ill solve right now....

Answer 10

wait do i use trigonometry? my brain is blank

Answer 11

no wait

Answer 12

I did 180-(35+25)= 120 is that wrong?

Answer 13

No, that's correct. ^.^

Answer 14

Picture not to scale, obviously.

Answer 15

so besides solving for x, is there anything i can write down about this triangle?

Answer 16

Idk. No matter the length of the sides, the interior angles always add up to 180 degrees.
Use this formula I gave you earlier for the sum of interior angles.
180(n - 2), where 'n' is the number of sides.

Answer 17

do i really need to or is it optional since i already solved and got x? Lets just move on to the next one

Answer 18

before moving on do you know what type of triangle that was?

Answer 19

Oh, yeah, I think this is a proof too. If all the angles are different, then it's a scalene triangle (all sides are different).
If 2 angles are the same, isoceles. (2 sides are equal)
All 3 angles are sale, equilateral.

Answer 20

Kay now this one

Answer 21

Don't you know trigonometric functions, and the special right triangle, 30-60-90 triangle?

Answer 22

i know now that you remind me that the triangle is a 30-60-90 but for the sides its missing both x and y and idk

Answer 23

Yeah, you have to use trignometric function with the given angle, 30 degrees. Do you know which ones we need for this one?

Answer 24

Nope

Answer 25

.-. Have you not learned about sine, cosine, and tangent?

Answer 26

But when 2 sides are missing im clueless

Answer 27

It doesn't matter. We just use the trig functions. That's what you would call a trap. c;
Ok, so. Do you know the definition of sine of an angle when it comes to triangles?

Answer 28

No i dont know

Answer 29

.-. Elisa, why you making my volunteering hard. >_>
Your EOC is tomorrow and you don't know about sine and stuff.
\[\sin(x) = \frac{opposite}{hypotenuse}\]

Answer 30

Look at the part with the triangles in it. Around the middle.

Answer 31

Actually its on Thursday and i know i have a very low chance of passing

Answer 32

And i was confused thinking you wanted a more complex definition

Answer 33

but idk how to apply that to this specific problem

Answer 34

@iPwnBunnies

Answer 35

sine of an angle = length of opposite side/length of hypotenuse.
\[\sin(30) = \frac{29}{x}\]
\[x = \frac{29}{\sin 30}\]
Do you know what the sin of 30 is? It's a special angle, so you shold know it. It's easy to remember.

Answer 36

hopefully your on OS when i get home bye :/

Answer 37

i got 58

Answer 38

@iPwnBunnies

Answer 39

Mhmm. Good to remember. sin(30) = cos(60) = 1/2

Answer 40

i will try 2 remember that

Answer 41

For side 'y' the remaining leg. We use tangent.
\[\tan(x) = \frac{opposite}{adjacent}\]

Answer 42

\[\tan(30) = \frac{29}{y}\]

Answer 43

50.22947342

Answer 44

Mhmm. tan(30) = 1/sqt(3) = sqrt(3)/3

Answer 45

kay now help me with another one plz

Answer 46

Use Pythagorean Theorem to figure out what the length of that rectangle is, breh.
Then area is length*height, or whichever two dimensions it gives.

Answer 47

It's a rectangle, with a diagonal going through it. So it forms two right triangles.

Answer 48

Okay i did pythagorean th. and then i used my answer in the area and i got 240

Answer 49

what about this one?

Answer 50

Yaaassss, gurl, yaasss.

Answer 51

Lmao thaaanksss and help me with the triangle ^

Answer 52

I'm drawing blanks. Y. ;-;

Answer 53

idk

Answer 54

@iPwnBunnies

Answer 55

are you giving up? do i have to wait for another good source of help to come online?

Answer 56

Has there been another source? -.-
I've helped you with maybe 20 questions in the last 3 days.

Answer 57

yes you are great but there are other ppl i look for depending whos online and whos not cuz if i sit here waiting ill fail for sure

Answer 58

hello? omg plz help me
