I need a little walkthrough i think i got this understand a little

[bleak oar]

Find <B in rhombus BCDE

do i set this equal to 180?

or do i set them equal to each other

[zinc mauve]

3x - 58 = 2x
solve for x
then <B = 180 - <C

[bleak oar]

x=58?

[zinc mauve]

yes

[bleak oar]

then that it?

[zinc mauve]

then find angle B

[bleak oar]

how do i do that?

sorry

[zinc mauve]

<B + <C = 180

[bleak oar]

huh?

idk what that means ngl

this is the main problem idk what to do after i set them equal to each other

[zinc mauve]

that's the property of parallelogram, same goes for rhombus

[bleak oar]

ok but now what do i do?

[zinc mauve]

you already know x, now calculate <C

[bleak oar]

how do i do that

yes im slow asf

[zinc mauve]

<C = 3x - 58
substitute the value of x

[bleak oar]

116

[zinc mauve]

yes

now <B = 180 - <C

[bleak oar]

64?

[zinc mauve]

yes

[bleak oar]

that the final answer?

[zinc mauve]

yes

[bleak oar]

YESSSS 1 more question then im doneeee

[zinc mauve]

sure

[bleak oar]

can u help me wit 1 more?

(9b-18)+3b=180?

[zinc mauve]

no

this one is about sides, not angles

[bleak oar]

set them equal to each other

[zinc mauve]

yes

[bleak oar]

the that comes out to 3b

after i do 6b=18

[zinc mauve]

DH = 3b
so you can just directly divide both sides by 2

[bleak oar]

oh so i was right?

[bleak oar]

this just makes it easier?

[zinc mauve]

yes

[bleak oar]

im bumb asf

[zinc mauve]

actually less steps

[bleak oar]

i accidently clicked 8 instead of 9
