Answer:

x = 323 in

Step-by-step explanation:

Given triangles are similar, so their corresponding sides would be in proportion:

3ft = 3*12 = 36 in

5ft 8 in = 5*12 + 8 = 68 in

14 ft 3 in = 14*12 + 3 = 171 in

\frac{3 \: ft}{14 \: ft \: 3 \: in}  =  \frac{5 \: ft \: 8 \: in}{x}  \\  \\  \frac{36}{171}  =  \frac{68}{x}  \\  \\ x =  \frac{171 \times 68}{36}  \\  \\ x =   \frac{11628}{36}  \\  \\ x = 323 \: in \:  \\  \\ x = 26 ft \: 11  in

What is 7.7 kilograms x 17 answer must be in kilograms
Andrew [12]

Answer:

<u>The correct answer is 130.9 kilograms.</u>

Step-by-step explanation:

We want to calculate what is the result of 7.7 kilograms multiplied by 17 and the answer should be in kilograms

Result = 7.7 kilograms * 17

Result = 7.7 * 17

Result = 130.9

Result = 130.9 kilograms

<u>The result of the multiplication of 7.7 kilograms by 17 is exactly 130.9 kilograms</u>

Answer:

hello :

the perimeter is : p = 2(w +l)

w :width.... l : the  length

54 = 2(w + 23.5)

w+23.5 = 27

w =23.5 ft

Geometry help please how do I do these?
trapecia [35]

Answer:

Question 7:

∠L = 124°

∠M = 124°

∠J = 118°

Question 8:

∠Q = 98°

∠T = 98°

∠R = 82°

Question 15:

m∠G = 110°

Question 16:

∠G = 60°

Question 17:

∠G = 80°

Question 18:

∠G = 70°

Step-by-step explanation:

The angles can be solving using Symmetry.

Question 7.

The sum of interior angles in an isosceles trapezoid is 360°, and because it is an  isosceles trapezoid

∠K = ∠J  = 118°

∠L = ∠M

∠K+∠J+∠L +∠M = 360°

236° + 2 ∠L = 360°

Therefore,

∠L = 124°

∠M = 124°

∠J = 118°

Question 8.

In a similar fashion,

∠Q+∠T+∠S +∠R = 360°

and

∠R = ∠S = 82°

∠Q = ∠T

∠Q+∠T + 164° = 360°

2∠Q + 164° = 360°

2∠Q = 196°

∠Q = ∠T  =98°.

Therefore,

∠Q = 98°

∠T = 98°

∠R = 82°

Question 15.

The sum of interior angles of a kite is 360°.

∠E + ∠G + ∠H + ∠F = 360°

Because the kite is symmetrical

∠E  = ∠G.

And since all the angles sum to 360°, we have

∠E +∠G + 100° +40° = 360°

2∠E = 140° = 360°

∠E  = 110° = ∠G.

Therefore,

m∠G = 110°

Question 16.

The angles

∠E = ∠G,

and since all the interior angles sum to 360°,

∠E + ∠G + ∠F +∠H = 360°

∠E + ∠G  + 150 + 90 = 360°

∠E + ∠G   = 120 °

∠E = 60° = ∠G

therefore,

∠G = 60°

Question 17.

The shape is a kite; therefore,

∠H = ∠F = 110°

and

∠H + ∠F + ∠E +∠G = 360°

220° + 60° + ∠G = 360°,

therefore,

∠G = 80°

Question 18.

The shape is a kite; therefore,

∠F = ∠H  = 90°

and

∠F +∠H + ∠E + ∠G = 360°

180° + 110° + ∠G  = 360°

therefore,

∠G = 70°.
