Answer

Since an isosceles triangle is a triangle that as two sides that are the same length and one side that isn't. We know that one side(the the side that is'nt the same lenght as the others) is 72cm and a triangle is 180 degrees then you would subtract 72 from 180 which would leave you with 108 then you would divide 108 to find the value of x which is 54.

Answer:

(a) scalene, see attachment

(b) acute, see attachment

Step-by-step explanation:

(a) The sides of the triangle all have different lengths, so the triangle is scalene. Differences in coordinates between the points of the triangle are (6, 2), (5, 2), and (4, 1), so no two distances between these points can be the same.

(b) The angle opposite the longest side is clearly an acute angle, so the triangle is an acute triangle.

(c) Miles and Brad live on the same north/south line. Jose lives at a distance that is halfway between those houses in the north-south direction. Hence the distance to Miles' and Brad's houses must be the same from Jose's house. That means the triangle connecting Miles', Brad's, and Jose's houses will be an isosceles triangle.
