Answer: The diagonals are perpendicular.

The diagonals are congruent to each other.

The diagonals bisect the vertex angles.

The diagonals bisect each other.

Step-by-step explanation:

A square is a quadrilateral whose all sides are equal in measure and all angles are right angle.

It is also a rhombus and the diagonals of rhombus are perpendicular bisector of each other .

Therefore, for square the true statements are:-

The diagonals bisect each other.

The diagonals are perpendicular.

The diagonals are congruent to each other. If we divide the square in two triangles, we will see the triangles will be congruent by SSS congruenct rule.{side diagonal side}

⇒ The diagonals bisect the vertex angles. [ by CPCT]

Write an equation in point-slope form and in slope-intercept form.

Sever21 [200]

The point-slope form:

$y-y_1=m(x-x_1)$

The slope-intercept form:

$y=mx+b$

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (1, -5) and (-3, -7). Substitute:

$m=\dfrac{7-(-5)}{-3-1}=\dfrac{12}{-4}=-3\\\\y-(-7)=-3(x-(-3))\\\\\boxed{y+7=-3(x+3)}$

Rewrite to the slope-intercept form:

$y+7=-3(x+3)$ use distributive property

$y+7=-3x-9$ subtract 7 from both sides

$\boxed{y=-3x-16}$

-9 + 2x + 5x

3: Combine like terms

-9 + 2x + 5x

-9 + 7x

4: Rearange terms

-9 + 7x

7x - 9

Solution

7x - 9

A rescue helicopter flew from its home base for 35 kilometers on a course of 330 degrees to pick up an accident victim. It then

artcher [175]

I've drawn a triangle to represent the journey (see attached.

The angle from Home to Victim to Hospital is:

a = $90 - (360 - 330) = 90- 30 = 60^o$

Using the cos rule, we can solve for the length x:

$a^2 = b^2 +c^2 - 2bccosA
\\x^2 = 35^2+25^2-2(35)(25)cos60
\\x^2 = 1850 - 875
\\x^2 = 975
\\x = \sqrt{975}
\\x = 31.2249...$

Using the cos rule, we can solve for angle b:

$a^2 = b^2 +c^2 - 2bccosA
\\35^2 = 31.22...^2+25^2-2(31.22...)(25)cosb
\\1225 = 975 + 625 - 1561.249...cosb
\\-375 = -1561.249...cosb
\\b = cos^{-1}( \frac{-375}{-1561.249...}) 
\\b = 76.1...$

So the bearing the helicopter has to travel is:

270 - 76.1 = 193.9 degrees (1 dp)

And the distance it travels is 31.2 km (1 dp)
