The two figures are similar. Find the missing

Answers

Answer:

4 in

Step-by-step explanation:

For the smaller figure, we can assume the other missing side is 2 because the area is 4, and area = length*width.

So the area of the larger figure is 4^2, or 16, so then we can assume the x or the two missing sides for the larger figure are 4 beacuse 4*4=16

Answers

Answer:

y=5x+13

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-(-2))/(-2-(-3))

m=(3+2)/(-2+3)

m=5/1

m=5

y-y1=m(x-x1)

y-(-2)=5(x-(-3))

y+2=5(x+3)

y=5x+15-2

y=5x+13

Answer:

y = 5x + 13

Step-by-step explanation:

Slope = delta y/ delta x

(3-(-2))/(-2-(-3))

(5)/(1) = 5

Slope = 5

y = 5x + b

Find the y-intercept through substitution:

(-2,3)

3 = 5(-2) + b

3 = -10 + b

13 = b

Equation:

y = 5x + 13

Find the surface area of a square pyramid with side length 5 ft and slant height 7 ft.
5 ft
5 ft

Answers

Answer:

99.33ft^2

Step-by-step explanation:

The surface area of a square pyramid is expressed as;

TSA = a²+2a√a²/4 + h²

Given that

a = 5ft

h = 7ft

Substitute

TSA = 5²+2(5)√5²/4 + 7²

TSA = 25+10√25/4 + 49

TSA = 25 + 10√(221/4)

TSA = 25 + 10(√55.25)

TSA = 25 + 10(7.433)

TSA = 25 +  74.33

TSA = 99.33ft^2

Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

Answer:5x5=25 fts

4(1/2 x 5ft x7 ft) = 70 fts

Add them up and you get

Answer= 95fts

Answer:

(6P-4M)(6P+4M)

Step-by-step explanation:

[tex]36P^2-16M^2[/tex] can be factored using the "difference of squares" formula which is [tex]a^{2}-b^{2}=(a+b)(a-b)[/tex].

6*6=36 and 4*4=16; P*P=P^2 and M*M=M^2 -- from this we know that the two variables on each side of the minus sign are perfect squares. Now, see [tex]36P^2-16M^2[/tex] as [tex](6P)^2-(4M)^2[/tex] to make it fit nicer to the formula.

So, [tex](6P)^2-(4M)^2=(6P+4M)(6P-4M)[/tex].

If you forget the formula, you can always go backward on multiple-choice questions like this one. Use FOIL to expand your factored answers.

Answer:

Step-by-step explanation:

The measure of an arc and its central angle are the same.

  ∠DCE = 68°

__

The measure of an inscribed angle is half the measure of the arc it subtends. Angle EDF is the degenerate case of an inscribed angle that has one ray of zero length. The relationship to the arc measure remains the same.

  ∠EDF = 34°

∠DCE = 68°

In ΔDEF, the measure of ∠F=90°, the measure of ∠D=20°, and EF = 92 feet. Find the length of FD to the nearest tenth of a foot.

Answers

Answer:

FD ≈ 252.8 feet

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(20°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(20°) = [tex]\frac{EF}{FD}[/tex]

0.36397 = [tex]\frac{92}{FD}[/tex]

FD = [tex]\frac{92}{0.36397}[/tex]

FD = 252.77

FD ≈ 252.8 feet

The sides of an isosceles triangle are 5, 5, and 7. Find the measure of the vertex angle to the nearest degree.

Answers

Answer:

T.A = 54 + 9/2 √3

Step-by-step explanation:

∵ The figure is triangular prism

∴ T.A = perimeter of the base × height + 2 × area of the base

∵ The base is an equilateral Δ with side length 3"

∴ The perimeter of the base = 3 × 3 = 9 inches

∴ The area of the base = 1/4 S² √3 = 1/4 (3)²√3 = 9/4 √3 inches²

∵ The length of the height of the prism = 6"

∴ T.A = 9 × 6 + 2 × 9/4 √3 = 54 + 9/2 √3

∴ T.A = 54 + 9/2 √3 inches²

In AVWX, XV
W X and mW
- 27°. Find m_X.

Answers

Answer:

m<X = [tex]126^{o}[/tex]

Step-by-step explanation:

From the given isosceles triangle, we have;

<W and <V as the base angles

So that,

m<W = m<V = 27 (base angles of an isosceles triangle are equal)

Thus,

m<X + m<V + m<W = 180 (sum of angles in a triangle)

m<X + 27 + 27 = 180

m<X + 54 = 180

m<X = 180 - 54

       = 126

m<X = [tex]126^{o}[/tex]

Answer:

  q = 9

Step-by-step explanation:

The angle bisector divides the triangle sides proportionally.

  q/36 = (16 -q)/28

  7q = 9(16 -q) . . . . . . multiply both sides by 252 (the LCM of 28 and 36)

  16q = 16(9) . . . . . . . . add 9q to both sides

  q = 9 . . . . . . . . . . . . . divide by 16

_____

Additional comment

We are given the sum of the segment lengths on the far left side. The proportion is the same for the sum of sides as it is for individual sides.

  (q/36) = 16/(36+28)

  q/36 = 16/64 = 1/4

  q = 36/4 = 9
