WebQuestion: In the right-angled triangle ABC, cosC=(4)/(5). Find angle A. NOT TO SCALE. In the right-angled triangle ABC, cosC=(4)/(5). Find angle A. NOT TO SCALE. Expert Answer. Who are the experts? Experts are tested by Chegg as specialists in their subject area. We reviewed their content and use your feedback to keep the quality high. WebThales' theorem states that if A is any point of the circle with diameter BC (except B or C themselves) ABC is a right triangle where A is the right angle. The converse states that if a right triangle is inscribed in a circle then the hypotenuse will be a diameter of the circle.
