How many triangles are in a 25 sided polygon?
23 of them because total angles are (25-2)*180 = 4140 degrees
If Triangle R'S'T' has sides of 3 cm 4 cm and 5 cm. And triangle RST has sides of 12 cm 16 cm and 25 cm. what is the dilation of the triangles?
The 1st is a right angle triangle and the 2nd is a scalene triangle.
What triangle has 25 degrees?
Many triangles can have 25° angles. In a right triangle, for example, where one of the non-90° angles is 65°, the other must be 25°. Note: If this question is from work you have been assigned by a teacher or professor, I suggest you do the work yourself instead of trying to find the answers online. This will help you to better understand the material and become more familiar with it. Of course, if this question was not from homework, you can disregard this message.
What is the area of a triangle 25' by 25'?
312.5 ft2
What is a triangle called with 25 degrees and 140 degrees?
Since the sum of the angles of a triangle = 180c, then the third angle is 15 degrees, Since the three angles are all different in size 140,25, & 15, this makes the three sides of different lengths. Since the three angles are all different then it is a scalene triangles, also one angle is greater than 90 degrees , at 140 degrees. This makes the angle obtuse. So overall the triangle is an obtuse scalene triangle.
