Question

I Need some help i have been doing this forever typing to figure it out. will Fan and Medal

Answer 1

thats what i have to do. sorry thought i clicked the whole picture.

Answer 2

Okay start by calculating the length of the base of the triangle with angle 36

Answer 3

idk how to do that..

Answer 4

Hint: Trigonometric Ratios

Answer 5

sorry but i think it in this way

2x-12=36

2x = 48

x = 48/2

x = 24

Answer 6

@jhonyy9 2x-12=36 is an assumption

Answer 7

they are not equal

Answer 8

And a false assumption looking at the fact that both triangles have different values of length for perpendiculars

Answer 9

i haven't done trigonometric ratios or whatever it is.

Answer 10

that just confused me even more...

Answer 11

not this side with one line y

and write sin36 = 6/y

so in this way you can calculi y and bc. you can use this in the other part too with side 5 and here on the left part this y will be y too so you can using sin(2x -12) = 5/y

in this way you can getting the value of 2x-12

hope you understand me

Answer 12

@jhonyy9 I just pondered on the fact that you cant apply trigonometric ratios since it isn't a right angled triangle

Answer 13

so than i think here is something mistaque in the text of this exercise - or not ?

Answer 14

Yeah there's lack of information

Answer 15

thats all that is in the question (Sorry my computer was lagging)

Answer 16

Which chapter is this question related to?

Answer 17

what is your opinion about these ?

36° ---- 6
2x-12 --- 5
---------------

(2x-12)*6 = 5*36

12x -72 = 180

12x = 252

x=252/12

x = 21

Answer 18

there isnt a lack of information

Answer 19

lesson 6 unit 7 Triangle review (Message bored review not in lesson review.)

Answer 20

what is your opinion about these ?

36° ---- 6
2x-12 --- 5
---------------

(2x-12)*6 = 5*36 (The angles are not in ratio, this is a wrong equality)

12x -72 = 180

12x = 252

x=252/12

x = 21

Answer 21

bc. these other two sides are congruent so in this way i think you can using this

Answer 22

That's only applicable when both triangles are congruent. One side is not same so isn't applicable

Answer 23

so than how you wan solve it , in what way ?

Answer 24

I think there is lack of information.

Answer 25

@ganeshie8 please

Answer 26

@mathstudent55
@welshfella
@zepdrix

your opinion in this case ?

ty

Answer 27

i think all we can say is 2x - 12 < 36

Answer 28

x < 24

Answer 29

the 2 triangles are not congruent.
