Studdy Solution

STEP 1

What is this asking? Find the values of angles xx and yy formed by a line crossing two parallel lines, given other angles are 7070^\circ and 6868^\circ. Watch out! Don't mix up alternate interior angles with corresponding or vertical angles!

STEP 2

1. Find xx.
2. Find yy.

STEP 3

Alright, let's **start** with xx!
Notice that xx is an *alternate interior angle* with the 6868^\circ angle.

STEP 4

Remember, alternate interior angles are *equal* when formed by a line crossing parallel lines.
That's a *key* fact here!

STEP 5

So, we can **confidently say**: x=68x = 68^\circ Boom! We've got xx!

STEP 6

Now, let's **tackle** yy!
Similar to xx, yy is an *alternate interior angle* with the 7070^\circ angle.

STEP 7

And just like before, we know alternate interior angles are *congruent* when a line crosses parallel lines.

STEP 8

Therefore, we can **conclude**: y=70y = 70^\circ Yes! We've nailed yy too!

STEP 9

We found x=68x = 68^\circ and y=70y = 70^\circ.
Awesome!
