Circumscribe a circle about the given triangle. ​
Bas_tet [7]

Answer:

Step-by-step explanation:

To circumscribe a circle to a given triangle implies constructing a circle outside the triangle, so that it touches the three vertices of the given triangle externally.

The step requires bisecting two sides of the triangle so as to locate the center of the circle. Then with the center and one of the edges, draw a complete circle. The circles should be outside the triangle and passing through its three vertices.

The construction is as shown in the attachment to this answer.

In a list of all 3 digit numbers whose digits add up to 9, what is the median
castortr0y [4]

Answer:

Waddup bro. For your answer, think of it this way. What 3 digits will make up 9? 1 x 9 is 9. So that would work. find it out by trying out different combination that would make up 9. I'm not gonna write all of 'em but 3 digits would add up to 9. There are no other groups of numbers adding up to 9. 4. Add up the remaining digits, 5 + 5 + 0 + 3 = 13. 5.13 is more than 9, so 1 + 3 = 4.  To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers. So add all up the singe digits and divide it by how much there is.
