10a)  <u>x = 81</u>    <u>y = 30.5</u>

Isolate y

2y + 20 = x

2y = x- 20

y = x/2 - 10

Plug in for y

4y - 6 + 64 + x = 180

4(x/2 - 10) - 6 + 64 + x = 180

4x/2 - 40 -6 + 64 + x = 180

4x/2 + 18 = 180

4x/2 = 162

4x = 324

x = 81

Plug in for x

2y + 20 = x

2y + 20 = 81

2y = 61

y = 30.5

10b) <u>x = 47</u>

Isolate x

4x -12 = 3x + 35

x - 12 = 35

x = 47

11)

2. definition of parallelogram

3. < ABD ≅ < BDC

4. < CBD ≅ <BDA
