Solution:

Given:

\begin{gathered} m\angle3=65^0 \\ m\angle11=100^0 \end{gathered}\begin{gathered} m\angle2+m\angle3=180^0.............the\text{ sum of angles on a straight line} \\ m\angle2+65^0=180^0 \\ m\angle2=180-65 \\ m\angle2=115^0 \end{gathered}

Therefore, the measure of angle 2 is 115 degrees.

\begin{gathered} m\angle5=m\angle11.........................(alternate\text{ exterior angles are congruent\rparen} \\ m\angle5=100^0 \end{gathered}

Therefore, the measure of angle 5 is 100 degrees.

\begin{gathered} m\angle13=m\angle3.........................(alternate\text{ interior angles are congruent\rparen} \\ m\angle13=65^0 \end{gathered}

Therefore, the measure of angle 13 is 65 degrees.

if 4 inches represents 100 miles on a scale drawing,how long would a line segment be that represents 50 miles
spin [16.1K]
I think 2 inches. Because if 4 inches represents 100 miles, and we're trying to find how long is 50 miles. since 50 is half of 100. 2 is half of 4. so thats y i think its 2

Answer:  -2x + 5y = 8

Step-by-step explanation:

Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y

Substitute the values of x and y from the given coordinate  (6,4) to find the new constant, b, the y-intercept.

-2x + 5y = b

-2(6) + 5(4) = b

-12 + 20 = b

8 = b

Rewrite the original equation substituting the new b for the original -15

-2x + 5y = 8

What could be the ordered pairs representing vertices C and D of quadrilateral abcd so that the new fire department is congruent
ohaa [14]
Given that <span>a city grid of Anytown, USA is shown on the grid below. The fire department is represented by quadrilateral RSTU. Another fire department is opening in a different part of the city to maximize fire protection. The size of the new department's property must be congruent to the older department. Vertices A and B are plotted on the grid to represent two vertices of the new fire department quadrilateral ABCD.

Map of Anytown; the line y equals 7 is Main Road; the line y equals 3 is Rose Lane; the line y equals negative 1 is Crystal Avenue; the line x equals negative 4 is Brick Street; the diagonal line is Dogwood Drive; Old Fire Department forms quadrilateral with ordered pairs R at negative 4, 7, S at negative 1, 7; T at negative 1, 3; U at negative 4, 3; A is at 4, negative 1 and B is at 1, negative 1

Recall that t</span><span>wo shapes are said to be congruent if the lengths of the sides and the angles are the same.

For quadrilateral RSTU to be congruent to quadrilateral ABCD, then RS = AB, RU = AD, ST = BC and TU = CD

Also, the figure ABCD is a result of a rigid body translation of the figure RSTU.

Given that R is at point (-4, 7) and A is at point (4, -1), also given that S is at point (-1, 7) and B is at point (1, -1).

It can be seen that points AB is a result of refrecting points RS across the y-axis and then shifting the resulting points down by 8 units.

Thus, given point T as (-1, 3) and point U as (-4, 3), refrection of points T and U across the y-axis will result in points (1, 3) and (4, 3), then shifting the resulting points down by 8 units will result to points (1, -5) and (4, -5)

Therefore, the ordered pairs representing vertices C and D of quadrilateral ABCD so that the new fire department is congruent to the old fire department are C(1, -5) and D(4, -5).</span>
