HELP! will mark branniest answer

Answer 1

All the angles in a triangle will add up to 180 degrees.

Therefore, subtract all the given angles to find x.

180 - 20 -130 = 30

So the missing angle is 30 degrees.

Answer 2

Intro:

Hello!!! Princess Sakura here ^^

Explanation:

We should know that the sum of all the angles in the triangle add up to 180. So since we already know two we can add those two and then subtract it from 180 to find the missing angle or I like to write equations...

`20+130+x=180`

After we make an equation we would combine like terms...

`150+x=180`

Now all we have to do is subtract 150 on both sides to get our missing angle...

`x=30`

So the missing angle is 30°.
