Answer:

MN = 4

m∠MLN = 42°

Step-by-step explanation:

If ΔMLN is congruent to ΔYZX, then

ML ↔ YZ MN ↔ YX LN ↔ ZX ∠M ↔ ∠Y ∠L ↔ ∠Z ∠N ↔ ∠X

and all those correspondences are congruent when the triangles are congruent

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28. A table with 6 columns and 2 rows. T

Alexus [3.1K]

The solution is (5,2)

Step-by-step explanation:

From the third column the equation for sum of equivalent system is given as;

8x = 40

divide both sides by 8 to get value of x

8x/8 = 40/8

x=5

Using the value of x in the fifth column's first equation will be;

4x +4y =28

4(5) + 4y =28

20 +4y =28

4y= 28-20

4y=8

divide both sides by 4 to get y

4y/4 =8/4

y=2

The solution is x=5 and y=2 written as (5,2)

Given: PRST is a square

xxTIMURxx [149]

Answer:

$(1-\sqrt{2})a^2$

Step-by-step explanation:

Consider irght triangle PRS. By the Pythagorean theorem,

$PS^2=PR^2+RS^2\\ \\PS^2=a^2+a^2\\ \\PS^2=2a^2\\ \\PS=\sqrt{2}a$

Thus,

$MS=PS-PM=\sqrt{2}a-a=(\sqrt{2}-1)a$

Consider isosceles triangle MSC. In this triangle

$MS=MC=(\sqrt{2}-1)a.$

The area of this triangle is

$A_{MSC}=\dfrac{1}{2}MS\cdot MC=\dfrac{1}{2}\cdot (\sqrt{2}-1)a\cdot (\sqrt{2}-1)a=\dfrac{(\sqrt{2}-1)^2a^2}{2}=\dfrac{(3-2\sqrt{2})a^2}{2}$

Consider right triangle PTS. The area of this triangle is

$A_{PTS}=\dfrac{1}{2}PT\cdot TS=\dfrac{1}{2}a\cdot a=\dfrac{a^2}{2}$

The area of the quadrilateral PMCT is the difference in area of triangles PTS and MSC:

$A_{PMCT}=\dfrac{(3-2\sqrt{2})a^2}{2}-\dfrac{a^2}{2}=\dfrac{(2-2\sqrt{2})a^2}{2}=(1-\sqrt{2})a^2$

annesha travels at a rate of 50 miles per hour. morris is traveling 3 feet per second less than Aneesha. which is the best estim

Snowcat [4.5K]

The speed that Morris is travelling is 0.3 ft/s

<h3>Calculating the speed of a body</h3>

Speed is the ratio of distance covered with respect to time.

Given the following parameters

Speed of Annesha = 50mi/hr

Speed of Moris = 3ft/s less than Aneesha

Convert 50mi/hr to ft/hr

50mi/hr = 73.3ft/s

Speed of Morris = 73.3 - 3

Speed of Morris =70.3 ft/s

Hence the speed that Morris is travelling is 0.3 ft/s
