Answer:

see explanation

Step-by-step explanation:

Since KL = KM then the triangle is isosceles and the 2 base angles are congruent, that is

∠KLM = ∠KML, thus

y - 9 = x + 4 (add 9 from both sides )

y = x + 13 → (1)

The sum of the 3 angles in the triangle = 180°, thus

x + 4 + y - 9 + x + y + 3 = 180

2x + 2y - 2 = 180 ( add 2 to both sides )

2x + 2y = 182 → (2)

Substitute y = x + 13 into (2)

2x + 2(x + 13) = 182 ← distribute and simplify left side

2x + 2x + 26 = 182

4x  + 26 = 182 ( subtract 26 from both sides )

4x = 156 ( divide both sides by 4 )

x = 39

Substitute x = 39 into (1)

y = 39 + 13 = 52

Hence

∠K = x + y + 3 = 39 + 52 + 3 = 94°

What is the volume of a rectangular crystal with a length (1) of 2.2 cm, a width (w) of 2 cm, and a height
Virty [35]

Answer:

7.92 cm^3

Step-by-step explanation:

To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

The scale factor from S to M is 3/2 What is the scale factor from M to S
natita [175]

we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.

<h3></h3><h3>What is the scale factor from M to S?</h3>

Suppose we have a figure S. If we apply a stretch of scale factor K to our figure S, we can say that all the dimensions of figure S are multiplied by K.

So, if S represents the length of a bar, then after the stretch we will get a bar of length M, such that:

M = S*K

If that scale factor is 3/2, then we have the case of the problem:

M = (3/2)*S

We can isolate S in the above relation:

(2/3)*M = S

Now we have an equation (similar to the first one) that says that the scale factor from M to S is 2/3.

Then we conclude that if the scale factor from S to M is 3/2, then the scale factor from M to S is 2/4.
