What is the area of∆ABC?

To find the area of a triangle, you can use the formula:

Area = 1/2 * base * height

If you provide the base and height of ∆ABC, I can calculate the area for you.

The area of ΔABC can be calculated using the formula:

Area = (1/2) - base - height

Where:

- Base is the length of one of the triangle's sides.
- Height is the length of the perpendicular line segment from the opposite vertex to the base.

In this case, we can use the given information to find the area of ΔABC:

- Base (AB) = 10 cm
- Height (CD) = 6 cm

Plugging these values into the formula, we get:

Area = (1/2) - 10 cm - 6 cm

Area = 5 - 6 cm

Area = 30 cm²

Therefore, the area of ΔABC is 30 cm².

Given that 2sin2°=1,find at least one value of°.
