What’s is the value of n? HELP ASAP PLEASE
earnstyle [38]

Answer:

The answer should be 69°

Step-by-step explanation:

Each line is being cut by a transversal, that means that the degree on the other side of it, added with the given degree will add up to 180°

1. On the right, you need to find the interior angle where 160° is outside so you subtract 180° from 160° to find the angle inside. That gives you 20°

2. On the top left you have 131° so 180°-131°=49°

Next you add the angles you have and then subtract it from 180 to get the interior angle with n° outside.

3. 20°+49°=69°

4. 180°-69°=111°

Then you do the same thing as the beginning which would be n°+111°=180°

5. n°+111°=180°, that means n=69°

Hopefully that clears it up for you :)

Rewrite the decimal fraction as a decimal number.
Sergio039 [100]

Answer:

8.025

Step-by-step explanation:

If you count the zeros in 1000, it's three. Count three starting from the back of 25. Add 0 in front of 25 to make it a three digit number. You then put the decimal point with the whole number.

35 POINTS!!! PLEASE HELP !!!!!!!!!!!!!!

Answer:

The function is increasing from x = 0 to x = 1.

Step-by-step explanation:

A <u>function</u> is increasing when the <u>y-value increases</u> as the <u>x-value increases</u>.

A <u>function</u> is decreasing when the <u>y-value decreases</u> as the <u>x-value increases</u>.

From x = -2 to x = -1 the function is decreasing as the y-value decreases as the x-value increases:  

  • x-value -2 to -1 → increase
  • y-value 2 to 0 → decrease

From x = -1 to x = 0 the function is increasing as the y-value increases as the x-value increase:  

  • x-value -1 to 0 → increase
  • y-value 0 to 2 → increase

From x = 0 to x = 1 the function is increasing as the y-value increases as the x-value increase:  

  • x-value 0 to 1 → increase
  • y-value 2 to 8 → increase

Use the markings in the image to answer the following questions (drawing not to scale):
katrin [286]

First of all, we have to observe this triangles separated by the height. These small and big triangles are similar according to the Angle-Angle-Angle principle.


a. We can find all of these length using the cosine of the angle, Pythagoras theorem and the principle of the similarity of triangles.


b. According to the cosine of the angle we can write that, cosθ = 12/a = 5/13 and from here a = 31.2. After finding that using Pythagoras theorem, we can write that b=\sqrt{31.2^{2}-12^{2}} = 28.8. According to the similarity of the triangles, we can write that 31.2/d = 28.8/12 and d = 13. Applying Pythagoras theorem we find that c = 5.


c. We already gave the answer for this question in part b
