a/a+2 = 3/5 ,, can someone give me the step by step solution to this? or at least explain it to me :’)

Hey There!

Let's solve...

if a/b=c/d,then it will be a*d=b*c

Note: * means "×" or multiply

Let's continue...

So final answer is a=3

I hope it is helpful to you...Cheers!___________

Welp life just is hard

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
