Step-by-step explanation:

Answer:

a^2 + b^2 = c ^2

a = first leg

b = second leg

c = hypothenuse

225 + b^2 = 625

b^2 = 400 -> b = 20 meters

Answer:

C = 18

Step-by-step explanation:

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form

Solution:

A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.

The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).

A right angled triangle is a triangle with one angle equals to 90 degrees.

Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:

sin30 = 9 / C

0.5 = 9 / C

C = 9/0.5

C = 18

Answer:

-8 is the median

Step-by-step explanation:

Given list of numbers -20, -8, -13, -15, 2, 20, -16 ,14 ,-8 ,-3

First, we need to arrange the numbers in ascending order, from the smallest to the biggest number.

-20, -16, -15, -13, -8, -8, -3, 2, 14, 20.

The number which comes in the middle is the median.

Here, two numbers have come in the middle, -8 and -8. In this case, to find the median, we add those two numbers and divide it by 2. The answer would be the median:-

[tex]\frac{-8 + -8}{2}[/tex]

[tex]\frac{-8-8}{2}[/tex]

[tex]\frac{-16}{2}[/tex]

The answer is -8.  

Answer:

-8 is the median

Answer:

[tex]Area \ of \ sector = \pi r^2 \frac{\theta}{360} = \pi \times 5 \times 5 \times \ \frac{75}{360} = 16.35 = 16.4yd^2[/tex]

option 2

Answer:

Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:

Tan(θ) = y/x

Cos(θ) = x/(√(x^2 + y^2))

Sin(θ) = y/(√(x^2 + y^2))

Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:

Ctg(θ) = x/y

Sec(θ) = √(x^2 + y^2)/x

Csc(θ) = √(x^2 + y^2)/y

En este caso tenemos el punto (4, -3), es decir:

x = 4

y = -3

Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:

Tan(θ) = -3/4

Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5

Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5

Ctg(θ) = 4/(-3) = -4/3

Sec(θ) =  √(4^2 + (-3)^2)/4 = 5/4

Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3

Answer:

the value of x is 7.5

Step-by-step explanation:

Answer: 7/10

Step-by-step explanation:

Number of people surveyed = 60

Number of people who responded Yes = 42

The relative frequency will be the fraction of those who responded yes divided by the total people surveyed. This will be:

= 42/60

= 7/10.

The relative frequency is 7/10.

Given:

In a circle, two chords GE and JF intersect each other inside the circle at D.

Measure of arc EF = 90 degrees.

Measure of arc JG = 70 degrees.

To find:

The measure of angle EDF.

Solution:

Intersecting chords theorem: According to this theorem, if two chords intersect each other inside the circle then the measure of angle on the intersection is half of the sum of intercepted arcs.

Using Intersecting chords theorem, we get

[tex]m\angle EDF =\dfrac{1}{2}(arcEF+arcJG)[/tex]

[tex]m\angle EDF =\dfrac{1}{2}(90^\circ +70^\circ )[/tex]

[tex]m\angle EDF =\dfrac{1}{2}(160^\circ )[/tex]

[tex]m\angle EDF =80^\circ[/tex]

Therefore, the measure of angle EDF is 80 degrees.

Answer:

[tex](x - \frac{\sqrt{209} - 1}{8} )(x - \frac{-1 - \sqrt{209} }{8} )[/tex]

Step-by-step explanation:

FACTS TO KNOW BEFORE SOLVING :-

Quadratic Formula :-

Lets say , there's an equation ax² + bx + c.

[tex]=> x = \frac{-b + \sqrt{b^2 - 4ac} }{2a} \: or \: \frac{-b - \sqrt{b^2 - 4ac} }{2a}[/tex]

SOLUTION :-

According to the question ,

By using quadratic formula ,

[tex]x = \frac{-1 + \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4} \: or \: \frac{-1 - \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4}[/tex]

[tex]=> x = \frac{-1 + \sqrt{209} }{8} \: or \: \frac{-1 - \sqrt{209} }{8}[/tex]

[tex]=> (x - \frac{\sqrt{209} - 1}{8} ) \: and \: (x - \frac{-1 - \sqrt{209} }{8} )[/tex] are the factors of 4x² + x - 13.

Answer:

144.44 yards

Step-by-step explanation:

The formula to find circumference is: C = π · d

Since we already have most of the factors figured out, we just replace them with what we have.

C = 3.14 · 46 yrds

144.44 = 3.14 · 46
