Answer:

  m∠ADC = 86°

Step-by-step explanation:

The sum of angles making a straight angle is 180°, so we have ...

  (6x +52)° +(9x +23)° = 180°

  15x = 105 . . . . . subtract 75°, collect terms, divide by °

  x = 7 . . . . . . . . . divide by 15

m∠ADC = (9·7 +23)°

m∠ADC = 86°

<h3>∠ADC = 104°</h3>

Here given that ,

  • Line BDA is a straight line
  • Angles on the line BDA are ∠BDC & ∠ADC

As we know that , sum of angles on a straight line is always equal to 180° . So ,

=> ( 6x + 52 ) ° + ( 9x + 23 ) ° = 180°

=> 15x + 75° = 180°

=> 15x = 180° - 75°

=> 15x = 105°

=> x = 105°/15

=> x = 7°

Now , by the given information , we need to find the value of ∠ADC

  • ∠ADC = ( 9x + 23 ) °

Now substituting the value of x ,

⇒ ∠ADC = 9x + 23

⇒ ∠ADC = 9 ( 7 ) + 23

⇒ ∠ADC = 63 + 23

⇒ ∠ADC = 86°

URGENT!!!! Find the m&lt;2.
Leto [7]

Answer:

Hello! :) I hope I’m correct!!

Step-by-step explanation:

<em>I think the answer should be the second one.</em>

<u><em>the angle with the square at the corner is obviously a right angle, 90°. opposite angles have the same angle so opposite to it, angle 3 is also 90°. then add the angle 3 and the given angle (23°). 90°+23°=113° then subtract it to 180° (since a straight line is 180°). 180°-113°=67°</em></u>

<em />

<em>The steps:</em>

<em>To solve m< 2,</em>

<em />m< 2 = 180 - (90 + 23)<em />

<em />m< 2 = 180 - 113<em />

<em />m< 2 = 67<em />

<em />

<h3><em>Therefore, I think the answer should be 67 (second choice)</em></h3>

<em>i’m not really sure if this is the answer, but I hope this was helpful!! :)</em>

<em>if you have any questions about these steps, feel free to ask!</em>
