Answer:

∠A = 94º

∠C = 86º

Step-by-step explanation:

You just need to know that the sum of the two angles in a parallelogram must be equal to 180º. Let's make an equation.

(5y-3)+(3y+27)=180

Solve;

5y-3+3y+27=180

Combine like terms;

8y+24=180

Subtract 24

8y=180-24

8y=156

Divide by 8

y=\frac{156}{8}

Simplify.

y=\frac{39}{2}

Replace;

∠A = 5y-3

5(\frac{39}{2})-3\\ \frac{195}{2}-3\\ \frac{195-2*3}{2}\\

\frac{195-6}{2}

\frac{189}{2} =94.5≅ 94

----------------------------------------------------------------------------------------------

∠C =

3y+27\\3(\frac{39}{2})+27

\frac{117}{2}+27

\frac{117+27*2}{2}

\frac{117+54}{2}

\frac{171}{2}=85.5≅86

y = 7 + 3/5
y = 35/5 + 3/5
y = 38/5
y = 2*(38/5)
y = 76/10
---
lunch time:
z = 1/2
z = 5*(1/2)
z = 5/10
---
time switching classes:
w = 7/10
---
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (76/10 - 5/10 - 7/10)/6
x = (76 - 5 - 7)/(10*6)
x = (64)/(10*6)
x = (2*2*2*2*2*2)/(2*5*2*3)
x = (2*2*2*2)/(5*3)
x = 16/15

x = 1.0666666666
---
check:
y = 7 + 3/5
y = 7.6
z = 1/2
z = 0.5
w = 7/10
w = 0.7
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (7.6 - 0.5 - 0.7)/6
x = 1.0666666666
