Lines AB and CD are straight lines. Find x and y. Give reasons to justify your solutions. I need both answers.
Kazeer [188]

Answer:

1) x = 14°, y = 5°

2) x = 18.5°, y = 37°

Step-by-step explanation:

1) ∠AOC and ∠BOD are vertical angles, then ∠BOD = 25°

∠MOD = ∠MOB + ∠BOD = 90°

3x + 23° + 25° = 90°

3x = 90° - 23° - 25°

x = 42°/3

x = 14°

∠LOB = ∠LOM + ∠MOB = 90°

5y + 3x + 23° = 90°

5y = 90° - 23° - 3(14°)

y = 25°/5

y = 5°

2) ∠AOC and ∠BOD are vertical angles, then ∠BOD = 16°

∠EOB = ∠EOD + ∠DOB =  90°

2y + 16° = 90°

y = (90° - 16°)/2

y = 37°

∠DOF = ∠BOF + ∠DOB =  90°

4x + 16° = 90°

x = (90° - 16°)/4

x = 18.5°

Step-by-step explanation:

We know that in a parallelogram

  • Opposite sides are of equal length
<h3>The sides are,</h3>

\\ \:\:\:\:\sf {:}\dashrightarrow 5in,10in,10in,5in

<h3>we know,</h3>

\boxed{\sf Perimeter=Sum\:of\:all\:sides}

\\ \:\:\:\:\sf {:}\dashrightarrow Perimeter_{(Parallelogram)}=5+5+10+10

\\ \:\:\:\:\sf {:}\dashrightarrow Perimeter_{(Parallelogram)}=10+20

\\ \:\:\:\:\sf {:}\dashrightarrow {\underline{\boxed{\bf Perimeter_{(Parallelogram)}=30inches}}}
