Question

Urgent! It's due today!

Line A is parallel to line b. If the measures of <2 is 78o, what is the measure of <5?

Answer 1

The answer is 102 because you subtract 180-78.

Answer 2

∠7 = 102°

Explanation:

∠2 ≅ ∠6 [Corresponding Angles]

So,

∠6 = 78°

Now,

∠6 + ∠7 = 180°

Where ∠6 = 78°

78° + ∠7 = 180°

∠7 = 180° - 78°

∠7 = 102°

Hope this helped!
