In triangle ABC, angle C is 90 degrees, BC is 7; sin A is 0.5. Find AB
| May 15, 2021 | education
To solve it, you need to remember the formula for finding sin A, the formula:
sin A = BC / AB;
Let’s transform the formula:
AB = BC / sin A;
substitute the data from the problem: BC = 7, sin A = 0.5;
AB = 7 / 0.5;
AB = 7 * 10/5 = 70/5 = 14.
Answer: the side of the triangle is ABC, AB = 14.
