Then do 10/7 * 1/5 to get 10/35 and then simplify to 2/7

You’re correct in the sense that you do 10/7 divided by 5, which can also be written as 5/1. But when you divide fractions, you have to flip the denominator and multiply that by the numerator. That means 10/7 *1/5 = 10/35 = 2/7

Oh I forgot to flip the denominator

I have a question about some geometry

I have a triangle and I know one angle measure is 70 degrees and that another angle is equal to 4a-4 and the other angle is blank how do i solve for 4

<:KekFull:802560939500503041> "how do you solve for 4?" it's 4

can you give us the question/diagram?

Er

I meant A lol

Ye, i usually don’t need help I just happened to miss the class

it's alright

the third angle is blank?

what is the triangle type?

I don’t understand the D@ and the d+the triangles angles

I just realized they’re congruent though

To solve would it be 4a-4=48?

Yes, I believe so.

@Seal

I got 13 for both

I set 5b-3 equal to 62

What’s an asa postulate?

@isoboto I think the top equation is wrong. 180-70-48 is not right. I think you'd use 62 instead of 48.

where would the 62 comes from 👀 180 - 48?

Well

You can assume the angle measure of the last angle

it's angle-side-angle

Idk what that means

oh, cuz you said it's congruent triangles. for congruent triangles, it means all the 3 sides & 3 angles are the same

What about sss

And sas

if 2 triangles are actually congruent, then angle Z = angle S

side-side-side. sas is side-angle-side

I mean for proving the congruence if that’s any different

I'm too far out of math classes for this. I was playing that X=R, Y=S, & Z=T.

okay gimme one sec

Like this

Everything is already given to you. Just label the diagram and you will know which congruent tyle you are dealing with

in this example, you know the two angles and one side, therefore it can only be asa
