Question

Help pls show work too :)

Answer 1

Answer:

60 degrees

Step-by-step explanation:

because two inner angles equals the opposite side's outer angle, we can do this

3y + 13 + 4y = 118

we combine like terms

7y + 13 = 118

subtract

7y = 105

and then divide

y = 15

then we do the equation for A's angle

4(15) = 60
