The measure of < A is 45 degree

Mathematics

We are given \triangle ABC \cong \triangle EFG

The order of the letter sequence is important. The letters pair up based on how they are arranged. We see that A and E are the first letters of the sequences. So this means that angles A and E are the same measure

angle A = angle E

3x+20 = 5x-80

3x-5x = -80-20

-2x = -100

x = -100/(-2)

x = 50

Use this x value to find the measure of angle A

angle A = 3x+20

angle A = 3(50)+20

angle A = 150+20

angle A = 170 degrees

<h3>Therefore, the statement "the measure of angle A is 45 degrees" is <u>false</u>.</h3>
