Question

How can I solve this problem?

Answer 1

Not sure about this one.

However; isn't it congruent?

Answer 2

I have someone to help you; more than me :3

Answer 3

What's the question ?

Answer 4

In attachments; he doesn't know how to solve that problem.

Answer 5

I thought I had to subtract from 180, but I don't know how to solve it because I don't usually work with that shape and I haven't touched on my geometry for a while.

Answer 6

Yes but that's just a figure. Are you trying to find 1, 2, and 3 ?

Answer 7

Can you help him? Not superior in math.


Wait, are you trying to find 1,2 and 3? I can help with that.

Answer 8

If you're looking for angles the sum is 360°.

Answer 9

I'm trying to find all of them, it says on my paper to find the missing measures.

Answer 10

I don't know the name of the shape though (I know, its being a while)

Answer 11

That's a trapeze. So 1=80° and 2=3 and 80°+80°+2*(angle 2)=360°
Solve for (angle 2)

Answer 12

Okay, so you are saying angle 1 is congruent to the angle given to us, and that to find the second angle I have to add those two and divide it by 360 or subtract it.

Answer 13

Yep angle 1 is congruent to the angle 80°. And angle 2 is congruent to angle 3.
And we know the sum of the angles is 360°.
1+80°+2+3=360° becomes 80°+80°+2*(angle 2)=360°

Answer 14

Because I think both, angle 2 and 3 are equal to a 100

Answer 15

That's correct !

Answer 16

Looks like Math has it covered ;w;.

Remember, congruence,

I will be in the English genre :).

Answer 17

so this is a trapezoid
- every two angles from the top and from bottom are congruent

Answer 18

so this mean that angle 1 has 80 degree too
so the sum of every 4 angles is 360 degree
- 80+80=160
- 360-160=200
so 200/2 =100
- this mean that angle 2 and 3 has a measure of 100 and 100 degree

hope this will help you
