Work out x.

[keen ore]

I

Ignore

[cobalt valley]

?

[cobalt valley]

ok

i cant do this one

[keen ore]

So ACB is 74°

[grizzled lion]

abc=74

bac=180-148

=32

[cobalt valley]

i need two answers

confusing

[grizzled lion]

sir

its

i. 74

[keen ore]

Explanation: Angles opposite to equal sides are equal

[grizzled lion]

ii. 32

[cobalt valley]

so 21

and 42?

[grizzled lion]

what

WHAT

i. 74 ii. 32

[cobalt valley]

different question

[grizzled lion]

yes

21

is correc

[cobalt valley]

and 42?

or 159

[grizzled lion]

138

[cobalt valley]

how you get that

[grizzled lion]

look to got 2 base angles

21 21

so add em

subtract from 180

[grizzled lion]

like usual

[cobalt valley]

so i add

69+69

[grizzled lion]

yes

[cobalt valley]

then 180-138

=42

so 69

and 42

[grizzled lion]

yes

[cobalt valley]

2x

that aint a nuber

website stupid

[grizzled lion]

GEEZ SOLVE FOR X

CBA=2x

LOOK THE TRIANGLE IS ISOSCLES

[cobalt valley]

idk what that is

never learnt this

[grizzled lion]

AND THERE A THEOREM WHICH STATES THAT OPPOSITE ANGLES OF 2 EQUAL SIDES OF TRINAGLES ARE EQUAL

[grizzled lion]

hy are u doing it then

[grizzled lion]

what grade?

id u dint mind

[cobalt valley]

im in year 9

im from uk

[grizzled lion]

9th grade

ok so if u didnt learn this whixh u shouldve why are u solving it?

[cobalt valley]

because my teacher says we learn it for homework

he set it today and due in a hour

[grizzled lion]

ok no she mustve taught isosceles trinagle theorem

u were absent?

[cobalt valley]

no

she probs dont know what it is

she aint a math teacher

[grizzled lion]

u know what isosceles trinagles are

[grizzled lion]

she passed 9th grade

[cobalt valley]

she actually didnt

she had to retake math

in colleage

[grizzled lion]

why is she goving u math hw if she dont teach math

i can explain to i

you*

[cobalt valley]

cause we have no teacher so we a pe teacher

[grizzled lion]

but on text its hard

[cobalt valley]

oh

[grizzled lion]

not rlly hard

just abnoyong

[cobalt valley]

ok

[grizzled lion]

to explain

its easy

when u get the hang of ot

you know what isosceles trinagles are

[cobalt valley]

there the same as triangles?

[grizzled lion]

ah geez i cant explain in text at all

[cobalt valley]

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case. Wikipedia

that it?

[grizzled lion]

yes

[cobalt valley]

ok

[grizzled lion]

alr

so there is a theorem

in whihc

[cobalt valley]

ok

[grizzled lion]

the angles opposte

to the same sides

are equal

[cobalt valley]

ok

[grizzled lion]

so

use that

[grizzled lion]

resend this

[grizzled lion]

so like i said

angles opposite to same side

are equal

according to isosceles trinagle theorem

[cobalt valley]

ok

[grizzled lion]

so

ACB = CBA

so CBA = 2x

so 2x+2x+x = 180

angle sum property of a triangle

so 180

addition of all angles

so x

=180/5

[cobalt valley]

36

is x

[grizzled lion]

ye

now u can find respective angles

[cobalt valley]

so is i 180?

2x = 72

[grizzled lion]

what

[cobalt valley]

x = 36

[cobalt valley]

the answer

[grizzled lion]

ye the

answer is

72

[cobalt valley]

so x is 36

[grizzled lion]

no

4x+4x+7x

=

180

now solve for x

[cobalt valley]

12

then 12 times 7

= 84

but i dont think right

[grizzled lion]

15x=180

[cobalt valley]

ye 12

[grizzled lion]

ye

[grizzled lion]

did u reallt

pull up

calculator

[cobalt valley]

ye

[grizzled lion]

💀

[cobalt valley]

idk what 180 divied by 15 is

[grizzled lion]

JUST DO DIVISION?

???

[cobalt valley]

15

30

45

60

75

90

[grizzled lion]

ehy are u recitint 15 table

[cobalt valley]

ye

[grizzled lion]

did u get it

[cobalt valley]

no

i only have 12
