Area of triangle = 1/2 ABsinC

Since all sides are equal, it means it is an equilateral triangle
⇒All angles are 60°

Area of triangle = 1/2 ABsinC
Area of triangle = 1/2 (3.5)(3.5)sin(60°)
Area of triangle = 5.3 in²

Find the diagonal of a square whose sides are of the given measure.<br><br> Given =
Contact [7]

Answer:

7\sqrt{42}

Step-by-step explanation:

The diagonal is the hypotenuse of the right triangle with legs 7\sqrt{3}

Use Pythagoras' identity to solve for the diagonal d

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

d² = (7\sqrt{3})² + (7\sqrt{3})²

    = 147 + 147

    = 294 ( take the square root of both sides )

d = \sqrt{294} = 7\sqrt{42} ≈ 45.37 ( to 2 dec. places )

Every morning Lucas runs 1 7/10 miles. How far does he run in 5 days?
dybincka [34]

1 (5) = 5

7/10(5/1) = 35/10

Simplify.

35/10 = 3 5/10 = 3 1/2

5 + 3 1/2 = 8 1/2

Lucas ran 8 1/2 miles in 5 days.

Find the distance between E(-3,4) and B(-1,6)​
Marrrta [24]

Answer:

The answer is

<h2>2 \sqrt{2 }  \:  \: or \:  \: 2.828 \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

E(-3,4) and B(-1,6)

The distance between them is

<h3>|EB|  =  \sqrt{ ({ - 3 + 1})^{2} +  ({4 - 6})^{2}  }  \\  =  \sqrt{ ({ - 2})^{2}  +  ({ - 2})^{2} }  \\  =  \sqrt{4 + 4}  \ \   \\  = \sqrt{8}</h3>

We have the final answer as

<h3>2 \sqrt{2 }  \:  \: or \:  \: 2.828 \:  \:  \: units</h3>

Hope this helps you
