Answer:

The value of x is 20.

Step-by-step explanation:

The steps are :

0.75x - 13 = 2

0.75x = 2 + 13

0.75x = 15

x = 15 ÷ 0.75

x = 20

Answer: x= 8

Step-by-step explanation:

According to the converse of basic proportionality theorem,

If in ΔABC , DE is a line drawn from AB to AC such that [tex]\dfrac{AD}{DB}=\dfrac{AE}{EB}[/tex]

then, DE is parallel to the third side BC.

Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have

[tex]\dfrac{LO}{OJ}=\dfrac{LN}{NK}\\\\\Rightarrow \dfrac{x-4}{x}=\dfrac{x-3}{x+2}\\\\\Rightarrow\ (x-4)(x+2)=x(x-3)\\\\\Rightarrow\ x^2-2x-8=x^2-3x\\\\\Rightarrow\ -2x+3x=8\\\\\Rightarrow\ x=8[/tex]

Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.

Answer:

3589.85763 meters

Step-by-step explanation:

Essentially, we must have e^(-0.00012h) = 0.65 since 0.65 = 65%

Taking natural log of both sides, we get

-0.00012h = -0.430782916

0.00012h = 0.430782916

h = 3589.85763

Answer:

i think it's 25.12.

Step-by-step explanation:

because you multiple 2x3.14×4

Given:

In an isosceles triangle,

One base angle = (4x-15)°

Vertex angle = 95°

To find:

The value of x.

Solution:

Let the triangle be ABC.

We have,

[tex]m\angle A=95^\circ[/tex]

[tex]m\angle C=(4x-15)^\circ[/tex]

Since ABC is an isosceles triangle and AB=AC, therefore, the base angles are equal.

[tex]m\angle B=m\angle C=(4x-15)^\circ[/tex]

Using angle sum property of triangles, we get

[tex]m\angle A+m\angle B+\angle C=180^\circ[/tex]

[tex]95^\circ+(4x-15)^\circ+(4x-15)^\circ=180^\circ[/tex]

[tex](8x+65)^\circ=180^\circ[/tex]

[tex](8x+65)=180[/tex]

On further simplification, we get

[tex]8x=180-65[/tex]

[tex]8x=115[/tex]

[tex]x=\dfrac{115}{8}[/tex]

[tex]x=14.375[/tex]

Therefore, the value of x is 14.375.

Answer: No, because the length of the diagonal is close to 9 feet.

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

it's indicated that all angles of this triangle are congruent; this means the triangle is called a 60-60-60 where all angles are 60 degrees.

If a triangle is equiangular then it is also equilateral, which means that if all angles are equal then all sides are equal.

Answer:

7= 2 4/5         8=2/21           9= 6 3/7          10= 1/6            11= 7/5           12=77/90

Step-by-step explanation:

3 1/5= 16/5-2/5=14/5 which equals to the same thing to 2 4/5

5/3= 35/21

11/7= 33/21

35/21-33/21= 2/21

3 3/4=15/4 times 12/7 straight ahead which is 180/28 equals to the same thing as 45/7 = 6 3/7

1/5 times 7/1 so u flip it over as u can see which is 7/5

2 1/5= 11/5    2 4/7= 18/7       11/5 times 7/18=77/90

Answer:

The side lengths are 17.9 feet and 35.8 feet

Step-by-step explanation:

Given lengths are;

40 feet, 3x feet and 6x feet

As the given triangle is right angled,

a = 3x, b = 6x and c = 40

Using Pythagorean theorem;

[tex]a^2+b^2=c^2\\(3x)^2+(6x)^2=(40)^2\\9x^2+36x^2=1600\\45x^2=1600\\[/tex]Dividing both sides by 45

[tex]\frac{45x^2}{45}=\frac{1600}{45}\\x^2=35.55[/tex]

Taking square root on both sides

[tex]\sqrt{x^2}=\sqrt{35.55}\\x=5.96[/tex]

Side lengths = 3x = 3(5.96) = 17.9 feet

and

6x = 6(5.96) = 35.8 feet

Hence,

The side lengths are 17.9 feet and 35.8 feet

Answer:

x=6

Sides= 36 & 18

Answer:

B. 4

Step-by-step explanation:

Hypotenuse (h) = 5

base (b) = 3

perpendicular (p) = a = ?

We know by using Pythagoras theorem we get

p = √( h² - b²)

= √ ( 5² - 3²)

= √ (25 - 9)

= √16

= 4
