Can someone plz help me I’m really confused on this.

Answer:

option c

Step-by-step explanation:

The angles are 30° , 60° , 90° . So its a right angled triangle . We can use trigo.

⇒ sin 30 = p/h

⇒ 1/2 = p/10

⇒ p = 10/2

⇒ p = 5

Using Cosine now ,

⇒ cos 30° = b/h

⇒ √3/2 = b/10

⇒ b = √3/2 × 10

⇒ b = 5√3

Answer:

(x + 4)² + (y - 2)² = 8

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (- 4, 2 ) , then

(x - (- 4))² + (y - 2)² = r²

(x + 4)² + (y - 2)² = r²

CA is the radius of the circle

To find r use the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = C(- 4, 2) and (x₂, y₂ ) = A(- 2, 4)

r = [tex]\sqrt{(-2+4)^2+(4 -2)^2}[/tex]

  = [tex]\sqrt{2^2+2^2}[/tex]

  = [tex]\sqrt{8}[/tex] , then r² = ([tex]\sqrt{8}[/tex] )² = 8

Then

(x + 4)² + (y - 2)² = 8 ← equation of circle

Answer:

7.22 feet

Step-by-step explanation:

From the question,

s = d/t................. Equation 1

Where s = speed of the space shuttle, d = distance traveled by the shuttle in an hour, t = time taken to travel the distance

make d the subject of the equation,

d = s×t.................... Equation 2

Given: s = 2.6×10000 feet per seconds, t = 1 hour =  3.6×1000 seconds.

Substitute these values into equation 2

d = (2.6×10000)/(3.6×1000)

d = 26000/3600

d = 7.22 feet.

Hence the shuttle travels 7.22 feet in an hour

Step-by-step explanation:

Sum of any two sides of a triangle must always be greater than the third side.

here 8 + 7 = 15 > 12

Hence, option C is the correct answer.

Answer:

x=2.371

Step-by-step explanation:

Subtract 8.63 from both sides

x+8.63-8.63=11.001-8.63

x=11.001-8.63

x=2.371

Step-by-step explanation:

The area of that should be painted by Kim is 55.75 ft².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that a container which is in shape of rectangular prism,

We need to find the area that should be painted,

So, to find the same we will find the surface area of the prism,

SA = 2(lh + hw + wl)

l = length, w = width and h = height,

SA = 2(2.50·4 + 2.75·2.50 + 2.75·4)

= 2(10 + 6.875 + 11)

= 2 × 27.875

= 55.75

Hence the area of that should be painted by Kim is 55.75 ft²
