The triangle has one angle of 100 degrees, and the other two are equal. 
We know that the angles of a  triangle always add up to 180. To find the measurement of angle 1 and 2, let's solve for this equation. 
2x + 100 = 180, where x=angle 1 = angle 2. Subtract 100 from both sides
2x = 80                                                           Divide both sides by 2
x = 40

URGENT!!!! Find the m<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>

F(13)=45,000(0.9)^13
Nadusha1986 [10]

Answer:

About 879.877

Step-by-step explanation:

To find f,

f(13) = 45,000(0.9)^13

13f = 45,000(0.25418658283)

13f = 11438.3962274

f = 879.877

Please tell me I did this the right way, Thanks!
