Answer:

   x = \sqrt{\frac{7}{2} }

Step-by-step explanation:

<u><em>Explanation</em></u>

From given graph

          AC = √7

 Given angle ∝ = 45°

    cos\alpha = \frac{adjacentside}{Opposite side}

   cos45 = \frac{x}{\sqrt{7} }

      \frac{1}{\sqrt{2} } = \frac{x}{\sqrt{7} }

       x = \frac{\sqrt{7} }{\sqrt{2} }

      x = \sqrt{\frac{7}{2} }

     x = 1.8708

What is the length of s
DIA [1.3K]
You can either solve this with the Pythagorean theorem or the special triangles rule which can be applied to (degrees —>) 45/45/90 or 30/60/90 triangles.

With the Pythagorean theorem: a^2 + b^2 = c^2 is used with the numbers accordingly- 5 and S are legs and can be either a or b while √50 being the hypotenuse can only be c

(5)^2 + (s)^2 =(√50)^2

25 + (s)^2 = 50

√ ((s)^2) = √ (50 - 25)

s = 5

The special Triangles rule actually states that a shortcut can be applied to the corresponding sides (look at picture). S is directly across from a 45 degree angle (and so is 5!)

If a = 5, than s must also = 5.

A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many
vodomira [7]

Answer:

The number of students who prefer chocolate milk is 780 .

Step-by-step explanation:

Given as :

The total number of students in the school = 1200

The percentage of students who prefer plain white milk = 35 %

Let the number of students who prefer chocolate milk = x

Now, ∵ The percentage of students who prefer plain white milk = 35 %

∴ The percentage of students who prefer chocolate milk = 100 % - 35 % = 65%

So , As The number of  students who prefer chocolate milk = x

Or, 65 % of total number of students in school = x

So, x = \frac{65}{100} × 1200

or, x = \frac{65\times 1200 }{100}

∴  x = 780

So, the number of students who prefer chocolate milk = x = 780

And  students who prefer plain white milk = 1200 - x = 1200 - 780 = 420

Hence, The number of students who prefer chocolate milk is 780 . Answer
