Find the area of a triangle if its two sides are 8 and 9 cm, and the angle between them is 30 degrees.

From the school geometry course, we know that the area of a given geometric figure can be calculated using half of the product of two sides and the sine of the angle that is between these sides.

Let us determine what the area of this triangle will equal, if from the condition of this problem we know for sure that the sides between which the angle is equal to 30 ° are 8 and 9 centimeters, respectively:

sin 30 ° = 1/2;

1/2 * 8 * 9 = 4 * 9 = 36.

Answer: The area is 36 cm2.
