PLEASE HELP!! the measures of two complementary angles are in the ratio 2:3. What is the measure of the smaller angle?
ivolga24 [154]
The answer is 36°.

Complementary angles are those angles whose sum is 90°.

Let angles be x and y.
x + y = 90°
x : y = 2 : 3
_____
3 * x = 2 * y
3x = 2y
x + y = 90°
_____
x = 2/3*y
x + y = 90°
2/3y + y = 90°
2/3y + 3/3y = 90°
5/3y = 90°
5y = 90° * 3
5y = 270°
y = 54°

x + 54° = 90° 
x = 90° - 54°
x = 36°

The smaller angle is 36°

In the circle above, LM = 2 and KL = 6.
9966 [12]

Answer:

C. 4

Step-by-step explanation:

We can use power of a point to solve this problem. From this, we can set up the equation:

MN^2 = LM x MK

MK would be the sum of LM and KL because of segment addition postulate. Therefore, we can say MK = 2 + 6 = 8

Now, we can substitute the values we have in the equation above:

MN^2 = 2 x 8

MN^2 = 16

MN = 4

Are vertical asymptotes determined by inspecting the numerator of a rational equation
Luden [163]

Hello!


Sadly no, vertical asymptotes are determined by setting the denominator of a rational function to zero and then by solving for x.
