How do I solve this?

Answer:

  (x, y) = (18, 5)

Step-by-step explanation:

Assuming the three lines meet at a single point at lower left (the figure is sloppily drawn), the angle (3x)°+49° is a corresponding angle to (7x-23)°. That means they have the same measure:

  3x +49 = 7x -23

  72 = 4x . . . . . . . . . add 23-3x

  18 = x . . . . . . . . . . . divide by 4

__

Angles (3x)° and (11y-1)° are "corresponding" angles, so are congruent.

  3x = 11y -1

  3(18) +1 = 11y . . . . add 1, fill in the value of x

  55/11 = y = 5 . . . . divide by 11

The values of x and y are 18 and 5, respectively.

Use the diagram to find the angle measures of the triangle. Recall that the sum of the angle measures of a triangle is 180 degre
My name is Ann [436]

Answer:

x =29

x+6 =35

4x = 116

Step-by-step explanation:

The sum of the angles of a triangle is 180

x+ (4x) + (x+6) = 180

Combine like terms

6x+6 = 180

Subtract 6 from each side

6x+6-6 = 180-8

6x = 174

Divide each side by 6

6x/6 = 174/6

x =29

x+6 = 29+6 = 35

4x = 29*4 =116

A geographer found that the land area of Aruba is 75 square miles and the land area of Bermuda is 19 square miles. Based on thes
MakcuM [25]

The interpretation of<em> </em><em>x</em> in the equation 75•x + 19•y = T, used by the geographer, based on the land area of Aruba, 75 m², and Bermuda, 19 m², is the population in a square mile of Aruba

<h3>Which method can be used to find the interpretation of <em>x </em>in the equation?</h3>

The land area of Aruba = 75 m²

Land area of Bermuda = 19 m²

The total number of residents is given in the question by the equation;

75•x + 19•y = T

Therefore;

x = The number of people in a square mile in Aruba

y = The number of people in a square mile in Bermuda

Which gives;

  • The interpretation of the variable, <em>x </em>in the context is the population of Aruba per square mile.
