Question

How do I setup and solve for y?

Answer 1

Could you tell the value of angle ABD from the figure?

Answer 2

I know that ABD is 90 degrees of the right angle symbol

Answer 3

okay, from the figure we know that
angle ABD= 3x = 90
Can you find value of x?

Answer 4

Do I just divide 90/3? Sorry for all the stupid questions

Answer 5

ok, let me explain
we have
3x= 90
divide both sides by 3
3x/3= 90/3
or
x= 90/3
Do you follow?
No question is stupid :)

Answer 6

ooohh, so how do I solve for Y?

Answer 7

what is the value of x you got?

Answer 8

x=30

Answer 9

good, what's the value of angle ABC?

Answer 10

ABC is 180 degrees

Answer 11

good, so what's angle DBC?

Answer 12

DBC is 90

Answer 13

good, also from figure
angle DBC= 2x+3y =90
so
we have
2x+3y=90

Can you solve for y? you already know the value of x?

Answer 14

I got y=10

Answer 15

yes, that's right. Good work.
