algol [13]

Step 1: arrange the data points in order
12 14 24 30 35 40 42 50 53 Step 2 : Find the median.
median is 35. Step 3. divide the data points into two : left and right
of median

12 14 24 30 and 40 42 50 53
Step 4: find median of each12 14 24 30 : (14+24)/2 = 1940 42 50 53 : (42+50)/2 = 46
step 5. draw lines on the scale on the median, two other
medians and least and the greatest value

Answer:

∠ A ≅ ∠ E

∠ K = 60°

Step-by-step explanation:

Part 1.

Given that ABCD ≅ EFGH.

Whenever a quadrilateral is congruent to another, and we write the congruency in symbol, then the order of congruency with respect to angles and sides are maintained in the symbol.

That means if ABCD ≅ EFGH, then ∠ A ≅ ∠ E, ∠ B ≅ ∠ F and so on.

Therefore, in this case, ∠ A ≅ ∠ E (Answer) {It is also shown in the diagrams}

Part 2.

Given that, Δ EFG ≅ Δ KLM

Hence, ∠ E ≅ ∠K, ∠ F ≅ ∠ L, and ∠ G ≅ ∠ M

It is also given that ∠ F = 35° and ∠ G = 85°

So, ∠ E = 180° - ∠ F - ∠ G = 180° - 85° - 35° = 60°

Since, ∠ E = ∠ K,

So, ∠ K = 60°. (Answer)

Answer:

x - 9

Step-by-step explanation:

(f ÷ g)(x) = f(x) ÷ g(x), that is

$\frac{x^2-19x+90}{x-10}$ ← factorise the numerator

= $\frac{(x-10)(x-9)}{x-10}$ ← cancel the common factor (x - 10) on numerator/denominator

= x - 9

What is the length of ST if RS=7?

nika2105 [10]

We can use tangent to calculate the length of ST.

$\sf tangent=\dfrac{opposite}{adjacent}$

Here, the opposite side of the 60 degree angle is ST, and the adjacent is RS. Plug in what we know, we can use 'x' for side ST:

$\sf tan(60\textdegree )=\dfrac{x}{7}$

Solve for 'x', multiply 7 to both sides of the equation:

$\sf x=7tan(60\textdegree )$

This is an exact answer for the length of ST, we can find an approximate with a calculator:

$\sf x\approx 12.12$
