Answer:
Area of rectangle = 225/2 or 112.5
Step-by-step explanation:
Given,
Consider a rectangle ABCD.
Let AC be a diagonal of rectangle of length = 15
In triangle ABC.
Sin 45° =height/hypotenuse {SinФ = height / hypotenuse}
Here, hypotenuse = diagonal of rectangle ( i.e AC = 15)
And height is AB
Therefore, sin 45° = AB/AC
or sin 45° = AB / 15
or 1/√2 = AB /15
AB = 15/√2
Similarly we can find Base (i.e BC) using cosine.
Cos 45° = Base/Hypotenuse
Cos 45° = BC / AC
or 1/√2 = BC/15
BC = 15/√2
Hence we got length of rectangle , AB= 15/√2
And width of rectangle , BC = 15/√2
Therefore, area of rectangle = Length × Width
Area of rectangle = 15/√2 × 15/√2 = 225/2
Hence, area of rectangle = 225/2 = 112.5
Answer:
thats alot of people don't you think
Step-by-step explanation:
The total number of people in the city surveyed by Annette= 480 people.
Step-by-step explanation:
Let 'X' be the Total Number of people Annette surveyed.
Out of Total people in the city, only <u>180 people are not interested</u> in a new shopping mall.
Therefore, it is given in the question that <u>180 is 37.5% of Total number of people surveyed (X).</u>
step 1: 180= (37.5/100)*(X)
step 2: X= (180*100)/37.5
step 3: X= 18000/37.5
step 4: X= 480
The correct answer is B.
Any square root that is not a perfect square is irrational. Root 3 is not a perfect square and therefore, it is irrational. Note the Root 16 is a perfect suare because 4*4=16
