Answer: The third one or C
Step-by-step explanation: That is the correct distance formula.
The answer to your question is 77 because the formula for area for a triangle is A=1/2BH and the base is 11 feet and the height is 14 feet. So, (14•11)/2 is 77. Therefore, 77 squared feet is the answer.
To find T, you add 25 to both sides, isolating the varible. This gives you T=-19
