Question 68245: Hi, could you please help me on how to solve this problem?
Determine the area of the triangle bounded by the following equations using Heron's formula: x-2y=12, x+3y=9, and 4x-y=-16. I know the Heron's formula but I do not know how to solve the problem. I first put the equations in function form but I don't know if that is how to solve the problem.
Please help me! I need this for homework that is due in three days!
Thank you.

Question 68325: Multi-Step Problem. You can use the method described below to approximate the distance across a stream without getting wet. As shown in the diagram you need a - Stand on the edge of the stream and look straight across to a point on the other edge of the stream. Adjust the visor of your cap so that its in the line with that point.
- Without changing the inclination of your neck and head, turn sideways until the visor is in line with a point on your side of the stream.
- Measure the distance BD between your feet and that point.
QUESTIONS
a.) From the description of the measuring method, what corresponding parts of the 2 triangles can you assume are congruent?
b.) What theorem or postulate can be used to show that the 2 triangles are congruent?
c.) Explain why the length of BD is also the distance across the stream.

Question 69010:
While you are in Washington, D.C., you visit the Washington Monument. In the scale diagram of a cross section of the monument you are given that AB= 8.4 meters, BC= 152.5 meters, ED= 17.6 meters, and CE= 5.25 meters.
NOTE: The diagram (Washington Monument) is a long rectangle with a triangle place on top of the rectangle. There is a dotted lined down the middle (or bisects)of triangle and goes through the rectangle. The corner bottom right of the rectangle is A. The middle of A and the left side of the rectangle, which is not lettered, is B. The triangle is (Not lettered)DE. D being the point of the monument. The middle of Not lettered and E is C. D, C, and B are all on the dotted line.
The volume of a pyramid is 1/3hB, where h is the height and B is the area of the base. If the bottom portion of the Washington Monument continued to rise at the same steepness to form a single pyramid, how tall would it be?

Question 70459: Li went for a mountain-bike ride in a relatively-flat wooded area. she rode for 5 km in one direction, then turned around and peddled 3 km in another. finally she turned and rode 3 km in yet another direction. stopping, Li took out a map and drew her path. could Li be back at her starting point? Could her path be a right triangle?

Question 72576: The measures of the angles of a triangle are 3x, 2x-10, and x+40 degrees. Find the number of degrees in the difference between the measures of largest and smallest angles.
I tried:
2x-10=0
2x=10
x=10/2
x=5
And after that I replaced x by 5. My answer is 3*5=15, (2*5)-10=0, and 5+40=45.
Then, the difference between 45 an 0 is 45°
