Find the side of an equilateral triangle if its area is 25√3 cm2

Answer:

3, 130 degrees

Step-by-step explanation:

Angles TUW and VUW are congruent, so their opposite sides will be congruent as well

GF and IF are congruent, so their opposite angles will be congruent as well. 65 + 65 is 130 degrees.

Answer:

The quadrilateral ABCD is a parallelogram

Step-by-step explanation:

The vertices of the quadrilateral ABCD are;

A(-2 -2), B(5, -2), C(4, -3)and D(-3, -3)

The slope of segment [tex]\overline {AB}[/tex] = (-2 - (-2))/(5 - (-2)) = 0

The length of segment [tex]\overline {AB}[/tex] = 5 - (-2) = 7 (points having the same y-coordinates)

The slope of segment [tex]\overline {AD}[/tex] = (-3 - (-2))/(-3 - (-2)) = 1

The length of segment [tex]\overline {AD}[/tex] = √((-3 - (-2))² + (-3 - (-2))²)  = √2

The slope of segment [tex]\overline {DC}[/tex] = (-3 - (-3))/(-3 - 4) = 0

The length of segment [tex]\overline {DC}[/tex] = 4 - (-3) = 7 (points having the same y-coordinates)

The slope of segment [tex]\overline {BC}[/tex] = (-3 - (-2))/(4 - 5) = 1

The length of segment [tex]\overline {AD}[/tex] = √((4 - 5)² + (-3 - (-2))²)  = √2

Therefore;

The opposite sites of the quadrilateral ABCD are equal; [tex]\overline {AB}[/tex] = [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] = [tex]\overline {BC}[/tex]

Given that the slope of a line gives the inclination of the line on a graph, we have;

The opposite sites of the quadrilateral are parallel; [tex]\overline {AB}[/tex] ║ [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] ║ [tex]\overline {BC}[/tex]

Therefore the quadrilateral ABCD is a parallelogram because the opposite sides of the quadrilateral ABCD are parallel.

Answer:

Step-by-step explanation:

In an inequality, sign of greater than or less than decides that the graph of the line will be a dotted line.

And sign of greater than means area above the dotted line.

Table for input output values,

x          -4           0            4           6          

y          -3          -4           -5        -5.5

Plot these points and join them by a dotted line.

Now we shade the area above the dotted line to show the solution area of the inequality.

Answer: 72 Miles In 90 Minutes

Step-by-step explanation: First, you have to divide both 15 & 12 by 15, (which represents minutes), and you get 1 over 0.8. Next, you multiply 1 over 0.8 times 90, which gibes you 90/72. There is your answer! I hope that you found this helpful.

Here is the equation below:

15/12 divided by 15/15 = 1/0.8 x 90/90 = 90 MINUTES/72MILES

Sry there is no answer well actually the answer has an infinite amount of answers but you can't just pick one and say that's that and this is with all of them... sorry

i think 2 bags or 1 bags hope it helps

The area of the farmer's land is 54 square yards and number of bags needed is 2. The correct option is (B).

A triangle is a two dimensional shape bound by three sides. The sum of the interior angles of a triangle is 180°. The longest side of a triangle is always less than the sum of other two sides.

For the given diagram, the following data is given as,

Base of the upper and lower triangle is 6.5 + 2.5 = 9 yards.

And, the height is given as 6 yards.

Now, the area of the land can be given as,

Area of upper triangle + Area of lower triangle

⇒ 1/2 × 9 × 6 +  1/2 × 9 × 6

⇒ 54 square yards.

As per the question, the area of the land is more than the soil contained in 1 bag.

Which implies the number of bags required is given as 2.

Hence, the area of land and number of bags required is obtained as  54 square yards and 2 respectively.

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.
