barxatty [35]3 years ago
8 0

Answer:

diameter = 18 m

Step-by-step explanation:

46.26 = 1/2π(diameter) + diameter

46.26 = 1.57d + d = 2.57d

d = 46.26/2.57 = 18 m

Solve for x <br> Need help asap
vlabodo [156]

Answer:

x=55

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of 2x+6 corresponds with the angle marked as x+9. Therefore, its measure must also be x+9.

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

2x+6+x+9=180

Combine like terms:

3x+15=180

Subtract 15 from both sides:

3x=165

Divide both sides by 3:

x=\frac{165}{3}=\boxed{55}

Which sequences of transformations confirm the congruence of shape II and shape I?
mylen [45]

Answer:

1. When we reflect the shape I along X axis it will take the shape I in first quadrant, and then if we rotate the shape I by 90° clockwise, it will take the shape again in second quadrant . So we are not getting shape II. This Option is Incorrect.

2. Second Option is correct , because by reflecting the shape I across  X axis and then by 90° counterclockwise rotation will take the Shape I in second quadrant ,where we are getting shape II.

3. a reflection of shape I across the y-axis followed by a 90° counterclockwise rotation about the origin takes the shape I in fourth Quadrant. →→ Incorrect option.

4. This option is correct, because after reflecting the shape through Y axis ,and then rotating the shape through an angle of 90° in clockwise direction takes it in second quadrant.

5. A reflection of shape I across the x-axis followed by a 180° rotation about the origin takes the shape I in third quadrant.→→Incorrect option
