Question

How to do this? Please help!

Answer 1

what do you need to know how to do

Answer 2

the value of x @roberman228

Answer 3

there is a picture attached above @roberman228

Answer 4

It is an equilateral triangle. What can you say about the two other angles of the triangle?

Answer 5

x=45

Answer 6

No, could you answer my question, please?

Answer 7

What?

Answer 8

that they are equal, so x equals 45?

Answer 9

zehan mention me in your ? and i'll come to it

Answer 10

wait no, cause x is equall to the opposite inner angles? so x = 80?

Answer 11

Both angles in the triangle are equal. Sum of all angles in a triangle is how many degrees?

Answer 12

exactly, x=80

Answer 13

180. @ZeHanz

Answer 14

@Foreverisabell: so what is left for the two equal angles?

Answer 15

Im still confused.

Answer 16

all the angles have to equal 180 inside no?

Answer 17

Sum of angles is 180. One angle is 40. Sum of other two angles is 140.
The other two angles are equal, so 70 degrees each.

Answer 18

Oh alright thank you.

Answer 19

So that means x = 70 + 40?

Answer 20

Yes! See, it is not that hard...

Answer 21

can you help me with one more thing?

Answer 22

Sure!

Answer 23

I attached the picture.

Answer 24

I can see it ;)
If P is a centroid, then P divides QT into two pieces, QP and PT, with

QP:PT =2:1

Now you know the length of QP (=14), so what would be the length of PT?

Answer 25

14 + 14? zoo. 28?

Answer 26

*sooo

Answer 27

No, QP:PT=2:1, so QP is double the length of PT, so PT would be 7.
So total 14+7=21

Answer 28

oh okay now I get it.
