Answer 1

What number does inside triangle has to equal overall?

Answer 2

pythagorean theorem

Answer 3

it doesnt matter, I just have to find x according to my teacher @Zale101

Answer 4

A triangle will always have its interior angles added up to 180 degrees.

Answer 5

Correct?

Answer 6

okay, yes. But I still forgot how to solve for x...

Answer 7

Don't worry about solving for x now. First, look at what a triangle's interior angle has to add up to.

Answer 8

See what angles are we giving.

Answer 9

A+B+C=180 degrees interior angles total.

Answer 10

okay..

Answer 11

Let A=70, B=30, and C=x

Answer 12

okay...

Answer 13

\(A+B+C=180 \)

After plugging A=70, B=30, and C=x, we will get:

\(\Large70+30+x=180 \)

Answer 14

Now solve for x :)

Answer 15

is it like that for every question problem ??

Answer 16

Perhaps, i don't know what's your question problems. If it's like this question, then yes. You do the same procedure i did.
