In AKLM, mZK = 101° and mL = 67º. Which statement about the sides of AKLM
Iteru [2.4K]

Answer:

LM > MK > KL

Step-by-step explanation:

Given: ΔKLM , m∠K = 101° , m∠L = 67°

By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°

By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.

Note the angles:

m∠M = 12° ∴ Side LK = shortest

m∠K = 101° ∴ Side ML = longest

m∠L = 67° ∴ Side KM = in between

∴ LK < KM < ML

A) LM > MK > KL is your answer.

Coll
SCORPION-xisa [38]

Answer:

The answer to your question is 5.7

Step-by-step explanation:

Data

Point A = (2, 3)

Point B = (-2, 7)

Process

To find the distance between points A and B use the formula of the distance between two points, substitute and simplify.

Formula

dAB = \sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}

-Identify wich is the value of x1, y1, x2, y2

        x1 = 2   y1 = 3  x2 = -2  y2 = 7

-Substittion

dAB = \sqrt{(-2 - 2)^{2} + (7 - 3)^{2}}

-Simplification

dAB = \sqrt{(-4)^{2} + (4)^{2}}

dAB = \sqrt{16 + 16}

dAB = \sqrt{32}

-Result

dAB = 5.65 ≈ 5.7

Help! I don’t understand this
Papessa [141]

Answer:

1/2

Step-by-step explanation:

A sample space is a collection or a set of possible outcomes of a random experiment.

I have created the sample space for these data and attached it.  As you can see there are 16 possible outcomes.

To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.

(I have highlighted these in yellow).

Therefore, P(X>9) = 8/16 = 1/2
