AlexFokin [52]

Answer:

720 inches

Step-by-step explanation:

On her blueprint, which is 1/20 the size of the actual garden

the width of the garden is 36 inches.

What is the width of the actual garden?

Let width of the actual garden = x

1/20 of x = 36

1/20 * x = 36

x = 36 ÷ 1/20

x = 36 * 20/1

x = 720

x = 720 inches

The width of the actual garden = 720 inches

Answer:

yes , 33^2 + 56^2 = 65^2   and obtuse

Step-by-step explanation:

<h2><u>Question 3</u></h2>

make use of the Pythagoras theorem

which is :

c^2 = a^2 + b^2

where c is the hypotenuse.

now put the values in the equation

65^2 = 56^2 + 33 ^2

the answer is :

<u>yes , 33^2 + 56^2 = 65^2</u>

<u></u>

<h2><u>Question 4</u></h2>

<u />

note if :

c^2 = a^2 + b^2 ----------- right

c^2 < a^2 + b^2------------ acute

c^2 > a^2 + b^2------------- obtuse

hence :

16 + 30 > 38

therefore its : <u>obtuse </u>

If CD is the perpendicular bisector of AB, then the value of x is:
amm1812
In ΔCAD and ΔCBD,

CD = CD [ Common side ]

AD = BD [ CD is the perpendicular "bisector" of AB ]

∠CDA = ∠CDB [ CD is the "perpendicular" bisector of AB ]

Thus, ΔCAD and ΔCBD are congruent triangles. [ SAS congruency ]

If these triangles are congruent, then AC = BC.

2x = 3x -10

x = 10.
