Answer:

x=8

KN=24

LK is congruent to LM

LN is congruent to NL

Answer: x = 8

             MN = 52

             LK is congruent to LM

             LN is  congruent to NL

ΔKLN and ΔMLN have:

LN ≅ LN

∠K = ∠M = 90°

∠KLN = ∠MLN

=> ΔKLN ≅ ΔMLN

=> KN = MN

=> 7x -4 = 5x + 12

⇔ 2x = 16

⇔ x = 8

=> KN = MN = 7.8 - 4 = 52

Answer:

2

Step-by-step explanation:

[tex]\begin{cases} (x_1,y_1)=(-3,4) \\ (x_2,y_2)=(2,8) \end{cases} \\ m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

[tex]m = \frac{8 - 4}{2 - ( - 3)} \\ m = \frac{4}{2 + 3} \Longrightarrow \frac{4}{5} [/tex]

We have got the value of slope. Substitute in the slope-intercept form.

[tex]y = mx + b \\ \sf{m = slope}\\ \sf{b = y - intercept}[/tex]

Substitute and Rewrite the equation.

[tex]y = \frac{4}{5} x + b[/tex]

I will substitute (2,8) in.

[tex]y = \frac{4}{5} x + b \Longrightarrow \sf \small{Substitute \: \: the \: \: coordinate \: \: points \: \: in \: \: the \: \: equation}[/tex]

[tex]8 = \frac{4}{5} (2) + b \\ 8 = \frac{8}{5} + b \\ 40 = 8 + 5b \\ 40 - 8 = 5b \\ 32 = 5b \\ \frac{32}{5} = b[/tex]

Rewrite the equation by substituting the value of b.

[tex]y = \frac{4}{5} x + \frac{32}{5} [/tex]

[tex] \large \boxed{y = \frac{4}{5} x + \frac{32}{5} }[/tex]

Answer:

Not a triangle

Step-by-step explanation:

In order for a shape to qualify as a triangle, the interior angles must add up to 180°

These angles only add up to 56°, therefore it is not a triangle.

Answer:

obtuse

Step-by-step explanation:

You have an isosceles triangle. 2 of the sides are equal in length. Since, the third side is longer than than the other 2, it will form an obtuse angle. If the third side was shorter, you would have all acute angles.

Answer:

2.123842852 is the first answer

for part b it'll be 2.12

hope that helps

Step-by-step explanation:

Answer:

a) 2.123842862

b) 2.12

Step-by-step explanation:

Answer:

45.1°

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.  

Cosine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:

[tex]a^2=b^2+c^2-2bc*cosA\\[/tex]

Given triangle PQR, let ∠PQR = x, to find angle PQR, we use cosine rule:

[tex]PQ^2=QR^2+RP^2-2(QR)(RP)*cos(x)\\\\substituting:\\\\11.6^2=7.8^2+15.7^2-2(7.8)(15.7)cos(x)\\\\134.56=60.84+246.48-244.92cos(x)\\\\244.92cos(x)=60.84+246.48-134.56\\\\244.92cos(x)=172.76\\\\cos(x)=0.7054\\\\x=cos^{-1}(0.7054)\\\\x=45.1^o[/tex]

x = ∠PQR = 45.1°

Hello, the answer is [tex]\frac{8x-1}{15}[/tex]. I will attach a photo of my work, along with an explanation of each step.

I hope this helps! If you feel this helped, feel free to give me Brainliest. Have a good day, and good luck on your assignment. :)

Answer:

the answer is (8x-1)/15, like the other person said. to solve this you need common denominators, by multiplying each side by the other denominator.

Answer:

Solving |-7-1| we get 8

Step-by-step explanation:

We need to solve |-7-1|

Absolute value is non-negative number even the number has negative sign.

So, |a| = a or |-a|=a

So, solving |-7-1|

=|-8|

=8

So, Solving |-7-1| we get 8

Answer:

c

Step-by-step explanation:

2x-3 > 2x-5/2

⇒2x-3/1=2x-5/2

⇒(2x-3)×2=(2x-5)×1

4x-6=2x-5

⇒2x-1>0

⇒2x>1

⇒x>1/2

Answer:

[tex]2x - 3 > \frac{2x - 5}{2} \\ 2(2x - 3) > 2x - 5 \\ 4x - 6 > 2x - 5 \\ 4x - 2x > 6 - 5 \\ 2x >1 \\ \boxed{x > \frac{1}{2} }[/tex]

Answer:

The coordinates of the midpoint are;

(-6.5, -3)

Step-by-step explanation:

Here, we want to get the midpoint of the line segment

To get this, we use the midpoint formula;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

Thus;

(x,y) = (8 - 21)/2, (-10 + 4)/2

(x,y) = -13/2 , -6/2

(x,y) = (-6.5 , -3)

Answer:

Answer:

$5

Step-by-step explanation:

We are given that  profit equation

[tex]P(x)=-2x^2+20x+0[/tex]

Where x=Charges per pair of mittens

We have to find the charge per pair of mittens to make her max profit.

Differentiate equation w.r.t x

[tex]\frac{dP}{dx}=-4x+20[/tex]

[tex]\frac{dP}{dx}=0[/tex]

[tex]-4x+20=0[/tex]

[tex]4x=20[/tex]

[tex]x=5[/tex]

Again differentiate w.r.t x

[tex]\frac{d^2P}{dx^2}=-4<0[/tex]

Hence, the profit is maximum at x=5

Lily should charge $5 per pair of mittens to make her max profit .
