Answer:

Step-by-step explanation:

Right angled triangle

Solve for hypotenuse

This is the formula c=√(a^2+b^2) so pug in the numbers a=24 b=7 √(24^2 + 7^2)=c=25

Answer:

X=25

Step-by-step explanation:

As by by Pythagoras theorem

24²+7²=x²

576+49=x²

625=x²

Taking square root on both sides

X=+25 and X=-25

As length cannot be negative so X= 25

Angle 4 would be 77degrees because angle two is vertical to angle four.

Angle 3 and Angle 1 are equal because they are vertical to each other.

You would subtract 180 (degrees) minus 77 (degrees) and get 103 (degrees).

So Angle 3 and Angle 1 would both be 103 degrees.

You would get 180 degrees from the line.

Given: sin ∅= 4/5 and cos x = -5/13 ; evaluate the following expression. tan( ∅ - x )

Pavlova-9 [17]

By definition of tangent,

tan(θ - x) = sin(θ - x) / cos(θ - x)

Expand the sine and cosine terms using the angle sum identities,

sin(x ± y) = sin(x) cos(y) ± cos(x) sin(y)

cos(x ± y) = cos(x) cos(y) ∓ sin(x) sin(y)

from which we get

tan(θ - x) = (sin(θ) cos(x) - cos(θ) sin(x)) / (cos(θ) cos(x) + sin(θ) sin(x))

Also recall the Pythagorean identity,

cos²(x) + sin²(x) = 1

from which we have two possible values for each of cos(θ) and sin(x):

cos(θ) = ± √(1 - sin²(θ)) = ± 3/5

sin(x) = ± √(1 - cos²(x)) = ± 12/13

Since there are 2 choices each for cos(θ) and sin(x), we'll have 4 possible values of tan(θ - x) :

• cos(θ) = 3/5, sin(x) = 12/13 :

tan(θ - x) = -56/33

• cos(θ) = -3/5, sin(x) = 12/13 :

tan(θ - x) = 16/63

• cos(θ) = 3/5, sin(x) = -12/13 :

tan(θ - x) = -16/63

• cos(θ) = -3/5, sin(x) = -12/13 :

tan(θ - x) = 56/33

Jared is going to plant 20 small plants around the edge of a circular garden that is 8 feet in diameter. If he spaces the plants

Hatshy [7]

Answer:

The space between the plants is approximately 1.26ft

Step-by-step explanation:

Given

Circular Garden

Number of plants = 20

Diameter of garden = 8ft

First, the circumference of the garden needs to be calculated; This is so because the plants that will be placed at the edge of the garden will occupy the circumference of the circle.

Calculating the circumference....

Circumference = 2πr

Where r = radius

r = ½ * diameter.

r = ½ * 8ft

r = 4ft

So,

Circumference = 2π * 4

Circumference = 8π ft

Given that the plants will be spaced evenly.

The distance between them = Circumference ÷ Number of plants

Distance = 8π/20

Distance = 0.4π ft.

Solving further to get actual distance (take π as 22/7)

Distance = 0.4 * 22/7

Distance = 8.8/7

Distance = 1.2571428571 ft

Distance = 1.26ft (Approximated)

Hence, the space between the plants is approximately 1.26ft

Solve for x. (4x + 4) + 4 = 4

soldier1979 [14.2K]

Answer: x = -1

Step-by-step explanation:

(4x + 4) + 4 = 4 subtract 4 from each side

(4x + 4) = 0 subtract 4 from each side again

4x = -4 divide each side by 4

x = -4/4

x = -1
