Assuming you want to solve for x:

Make 15x and 15 add up to 180 in an equation since they form a straight line. A straight line is 180 degrees.

15x + 15 = 180

  • Subtract 15 from both sides.

15x = 165

  • Divide both sides by 15.

x = 11

15 + 15 + 15x + 15x = 180

30 + 30x = 180

30x = 150

x = 5

Which set of shapes contains members that are always similar to one another?.
Viefleur [7K]
Answer: Equilateral triangles.

Explanation: We know that in similar polygons, its all the corresponding angles are congruent. Only the set of equilateral triangles contains members that are always similar( by AAA similarity criteria) to one another as the measure of all the angles of equilateral triangle is fixed i.e. 60°.
Rest other do not have fixed measure for angles in it.

Please help me on this question
Masja [62]

Answer:

The number is 5

Step-by-step explanation:

Let x be the number

3x+5+x = 25

Combine like terms

4x+5 = 25

Subtract 5 from each side

4x+5-5 = 25-5

4x = 20

Divide by 4

4x/4 = 20/4

x = 5
