Answer 1

@raffle_snaffle

Answer 2

okay I think i've got the answer...

Answer 3

@freckles can you explain it? I think you would be better at explaining it than me.

Answer 4

I guess we are assuming that one angle is 90 deg?

Answer 5

im thinking of solving x by using this
2(x+8) + (3x+1) + 90= whatever the total of angles is supposed to be for the interior of triangles.............

Answer 6

that's what I thought to but idk if you can just assume it's 90

Answer 7

if that one angle is 90 deg then your equation is right @daggiemib

Answer 8

but what would that number be? 180 is for the exterior i think

Answer 9

oh oops I thought I read you said 2(x+8)+(3x+1)=90

Answer 10

oh so i use that?

Answer 11

well I'm saying we can say that is we know that one angle is 90 deg

Answer 12

is it or is it not?

Answer 13

what i posted was all that was given to me

Answer 14

im assuming it is

Answer 15

this whole lesson is about angles of elevation and depression so yes right triangles are used

Answer 16

if that angle is 90 deg, none of the choices make sense
And I say this because 90+the other deg measurements for the other angles should equal 180 deg since it is a triangle

Answer 17

could it be two triangles on each other made into a rectangle?

Answer 18

in that case the degrees would be congruent

Answer 19

so this wasn't the picture?
