ZT=1/3 of CT. Therefore, CT=5
no
Assuming the configuration is as follows. With the triangle inside the square D B A E C Angle CBD = 90 & Angle ABC = 60, therefore angle ABD = 30 (90-60) We also know that angle DBE = 45 (half square) So DBE-ABD=ABE which is 45 - 30 = 15 Its a bit confusing without proper diagrams but it works.
25 inches - exactly.
If you mean: 8 12 16 and 10 15 20 then it is 4 to 5
If the sides of the triangle are 20 and 15 then by using Pythagoras' theorem the length of the hypotenuse works out as 25 units of measurement.

15
The area is 99.0 square units.
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees

82 degrees (180 degrees in a triangle)

180 sq in. ... that's (12 X 15)/2 equals 180.

The coordinates of the point P would be definitely 3 6.
