| November 27, 2020 | education
Given:
A = 0.4 cm
H = 0.8 cm
alpha = 60
Find: S -?
Decision:
We can find the area using the following formula:
S = 1 / 2a * b * sin alpha
S = 1/2 * 0.4 * 0.8 * 60 = 9.6
Answer: The area of the triangle along its two sides a and b and the angle alpha between them is 9.6.
