Answer 1

@mathmate @mathstudent55 @jigglypuff314

Answer 2

can anyone help i have been stuck in this for an hour

Answer 3

Hint:
use the following tools:
vertically opposite angles are equal.
the sum of angles of a triangle equals 180 degrees.
You'd be good to go.

Answer 4

wouldnt the triangle on the right side be 39

Answer 5

one of the sides

Answer 6

i am confused

Answer 7

yes

Answer 8

so those angles both equal 39?

Answer 9

which means x=51?

Answer 10

i mean x=52?

Answer 11

let being these angles y_1 and y_2
so than you can writing using what you know sure and what wrote above @mathmate that the sume of angles of a triangle is equal 180 degree
so in case of the right part triangle you can writing

x+y_1 +89 =180

and for triangle from the left part you can writing

51 +90 +y_2 =180 bc. this angle from this corner signid that is right angle - yes ?

Answer 12

so x= 52 right

Answer 13

idk

from this second equation you calculi the y_2 and bc. this is equal y_1 so using this knowladge you can calculi easy the value of x

Answer 14

so what would x be then if it isnt 52

Answer 15

so y_2 = 39 what mean that y_1 =39 too

Answer 16

yes both equal 39

Answer 17

so it would make x 52

Answer 18

so 39+89+x=180

x = 180-128

x= 52

Answer 19

yes

Answer 20

yes you are right

Answer 21

do you understand it now sure ?
