Question

The measure of ∠4 is 125°. Find the measure of ∠1

Answer 1

The measurement for <1 + <2 + <3 + <4 = 360°

<4 = 125°
Because angle <2 is opposite <4, we can conclude that it is also the same angle. Now we know the measurements for <2 and <4.

<1 and <3 are also opposite each other so their angles will be equal.

Can you solve the equation from here?

Answer 2

this is hard, iim sorry butim really not good at stuff like this

Answer 3

Here's a little more to help you:

360°-125°-125°=<1+<3 ( to get <1 alone, you must divide the answer by 2)

Answer 4

what do i have to divide by two?

Answer 5

This equation:
360°-125°-125°

Answer 6

ok, i will see what i get in then tell you

Answer 7

55?

Answer 8
