Solution:

<u>Note that:</u>

  • ∠A = 5x + 20
  • ∠B = 9x - 92
  • ∠A + ∠B = 180°

<u>Use the equation "∠A + ∠B = 180°" to solve for x and ∠A.</u>

  • ∠A + ∠B = 180°
  • => 5x + 20 + 9x - 92 = 180
  • => 14x - 72 = 180
  • => 14x = 252
  • => x = 252/14
  • => x = 18

<u>Now, find ∠A.</u>

  • ∠A = 5x + 20
  • => ∠A = 5(18) + 20
  • => ∠A = 90 + 20
  • => ∠A = 110°

Hoped this helped!

Answer:

x = 18°, ∠A = 110°

Explanation:

As the lines are parallel, their sums of total interior angle is 180°

∠A + ∠B = 180°

5x +20° +9x-92° = 180°

14x -72° = 180°

14x = 180° + 72°

14x = 252°

x = 18°

Solve for angle A:

∠A = 5x +20°

∠A = 5(18) +20

∠A = 110°

Zx and Zy are supplementary angles. Zy measures 108°,
gulaghasi [49]

Answer:

72°

Step-by-step explanation:

Given

Zy = 108°

Zx = ?

We know

Zx + Zy = 180° {being supplementary angles }

Zx + 108° = 180°

Zx = 180° - 108°

Zx = 72°

Hope it will help :)

Find the area of the striped sector if ∠ A = 45° and the circle has a radius of 10 inches.
Pie
A diagram must be provided along with the question above. Based on my research, here is what I got.

<span>100 pi is the area of the entire circle
 That makes :
</span><span>∠ A = 45°/360 = 1/8
</span> 100pi/8 = 25 pi / 2
 
The answer is option D)25π over 2. I hope this answer helps.
