A cottage has a gable roof. To the nearest foot, how wide is the cottage?A. 12 ftB. 24 ftC. 35 ftD. 70 ft
Sergio [31]

Answer: the answer is B: 24ft

Step-by-step explanation: To find how wide the triangle is identify your angles. You have a right angle which is equal to 90° and an angle that measures 46°. Add up both of these angles and you'll get 136°. A triangle can only have three angles that add up to 180. So subtract 180 and 136 you get 44. Multiply the hypotenuse by sin(46) to get the length of the side facing the opposite way of the angle that measures 44°. You will get 11.8 which is about 12. The other triangle is a congruent triangle meaning that it's angles and sides are the same. Add both 12's up and you have 24ft as your width for the cottage.

Enrico is designing a rectangular board for a game. He wants the ratio of the length to the
Aleks [24]

Answer:

A(x)=\frac{6}{5}x^2

Step-by-step explanation:

Let

y ----> the length of the board

x ----> the width of the board

we know that

\frac{y}{x}=\frac{6}{5}

y=\frac{6}{5}x ----> equation A

The area of the board is

A=xy ----> equation B

substitute equation A in equation B

A=x(\frac{6}{5}x)

A(x)=\frac{6}{5}x^2
