Question

CA = 21 см, CB = 28 см. (Дроби сокращай.) tg∢B= ; tg∢A= .

Answer 1

Ответ:

Объяснение:

$tgB=\frac{AC}{BC} =\frac{21}{28} =\frac{3}{4}=0.75\\tgA=\frac{BC}{AC} =\frac{28}{21} =\frac{4}{3} =1\frac{1}{3}$

Answer 2

To find the tangent of angles A and B, we can use the following formulas:

1. Tangent of angle A (tg∢A) is given by the ratio of the opposite side to the adjacent side in a right-angled triangle.

2. Tangent of angle B (tg∢B) is given by the ratio of the opposite side to the adjacent side in a right-angled triangle.

Given that CA = 21 cm and CB = 28 cm, we need to know the lengths of the opposite sides and adjacent sides to find the tangent of angles A and B. Without additional information or the measurements of the opposite sides, we cannot determine the exact values of tg∢A and tg∢B.

If you have more information about the triangle or the measurements of the other sides, please provide them so I can assist you further.
