11.3 rounded off because of a parallell
The two base angles are congruent or equal measure. Find one angle and use the 180 degree rule and you can find all three.
17/2 = 8.5 (where EN touches DF)Using Pythagoras...172 - 8.52 = 216.75Square root of 216.7 = 14.7

To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.

To find the perimeter of something all you have to do is, MEASURE THE DISTANCE AROUND THE OBJECT, for example if you have a triangle and the left side is 8cm, the right side is 5cm, and the bottom is 3cm, add the three measurements, 8cm + 5cm + 3cm = 16cm

The length on the map that represents 80m with a scale of 1cm to 5m would be 16cm. To find this, divide 80m by 5m to get 16. Then, scale it down to one centimeter.
To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.
Click the triangle of 1, and the wheel will turn. When you find another triangle at the hole, click the triangle of 2. When you find another triangle at the hole again, click the triangle of 3. When you find the last triangle at the hole, click the triangle of 4. At the hole, you will find the exit button, click on it. However, the 4th triangle is really hard to find!
