Help pls show work too :)

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

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
