Since the side BC is side AE.
Calculate the area of the triangle:
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Side AE is provided as 9. Since side BC is of side AE, we calculate:
Step 2: Because triangle ABC is involved in calculation, the area of triangle BCE becomes , and assumed height perfectly completes these side lengths within the triangle grid. Given no specific height, the functional area equals set simplification calculations:
Substitute the values to find the area of triangle BCE:
Calculate:
Therefore, the solution to the problem is .
27
Angle A is equal to 30°.
Angle B is equal to 60°.
Angle C is equal to 90°.
Can these angles form a triangle?
Look at the diagram carefully! The height is always perpendicular to the base. Here, AE = 9 is shown as a vertical line, making it the height. The base BC lies along the bottom.
The problem states "BC is side AE." This means BC = (2/3) × AE. So BC = (2/3) × 9 = 6.
Technically yes, but you must use the corresponding perpendicular height. It's easiest to use the base shown at the bottom (BC) with the vertical height (AE) from the diagram.
Double-check your steps: BC = (2/3) × 9 = 6, then Area = (1/2) × 6 × 9 = 27. Make sure you're using the correct formula and measurements!
Remember the triangle area formula includes (1/2)! If you calculated 6 × 9 = 54, you forgot to divide by 2. The correct area is (1/2) × 54 = 27.
