Find the length of the missing side of the right triangle.

kupik [55]

Answer:

39 units

<h3>Step-by-step explanation:</h3>

Since two side lengths and a right angle are given, we can use pythogoras theorem to determine the missing side (c) of the triangle. It should be noted that pythgoras theorem can only be used if the triangle is a right triangle.

<u>Pythogoras theorem formula:</u>

$(\text{Side}_{1} })^{2} + (\text{Side}_{2} )^{2} = (\text{Hyptenuse})^{2}$

Substitute the legs of the triangle and the hyptenuse

$\implies (36)^{2} + (15 )^{2} = (c)^{2}$

Simplify both sides of the equation

$\implies 1296 + 225 = (c)^{2}\\$

$\implies 1521 = (c)^{2}\\$

Take square root both sides

$\implies \sqrt[2]{1521 } = \sqrt[2]{c^{2} }$

Solve for "c" by simplifying the roots

$\implies \sqrt[2]{39 \times 39 } = \sqrt[2]{c \times c }$

$\implies \boxed{39 = c}$

Thus, the measure of the missing side length (c) is 39 units.

The coordinates of the vertices of parallelogram RMBS are R(–4, 5), M(1, 4), B(2, –1), and S(–3, 0). Using the diagonals, prove

REY [17]

To prove a rhombus you need to show that the sides are congruent and the diagonals are perpendicular.

Sides:

$d_{RM}=\sqrt{(-4-1)^2+(5-4)^2}$

$=\sqrt{(-5)^2+(1)^2}$

$=\sqrt{25+1}$

$=\sqrt{26}$

$d_{MB}=\sqrt{(1-2)^2+(4+1)^2}$

$=\sqrt{(-1)^2+(15)^2}$

$=\sqrt{1+25}$

$=\sqrt{26}$

$d_{BS}=\sqrt{(2+3)^2+(-1-0)^2}$

$=\sqrt{(5)^2+(-1)^2}$

$=\sqrt{25+1}$

$=\sqrt{26}$

$d_{SR}=\sqrt{(-3+4)^2+(0-5)^2}$

$=\sqrt{(1)^2+(-5)^2}$

$=\sqrt{1+25}$

$=\sqrt{26}$

$\overline{RM}$ ≅ $\overline{MB}$ ≅ $\overline{BS}$ ≅ $\overline{SR}$

Diagonals:

Use the slope formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$

$m_{RB}=\dfrac{5+1}{-4-2}$

$=\dfrac{6}{-6}$

= -1

$m_{MS}=\dfrac{4-0}{1+3}$

$=\dfrac{4}{4}$

= 1

Slopes are opposite reciprocals so they are perpendicular.

***************************************************************************

All of the sides are congruent and the diagonals are perpendicular so RMBS is a rhombus.

Sorry I’m really behind

Elina [12.6K]

The answer will be 238,900 miles.

If you round off 238, 854 to the nearest hundreds, you get

238,900 in miles.

Hope this helps!!!

A sequence of transformations maps ABC to AA'B'C. The sequence of transformations that maps A’B’C’ is

A (4,-4)
B (2, -8); and
C (6, -6)

followed by

A' (-2, 4)

C' (0, 6).

<h3>What is Transformation?</h3>

A transformation is a broad phrase that encompasses four distinct methods for changing the shape and/or position of a point, a line, or a geometric figure.

Hence, the sequence of transformations maps ABC to AA'B'C. The sequence of transformations that maps A’B’C’ is
