Question

В ABC AB=4, BC= 7, AC=6, а в MNK, если A=80°, B=60°

Answer 1

Ответ:

АВ:МК=4:8=1/2

ВС:KN=7:14=1/2

АС:MN=6:12=1/2

Answer 2

To find the side lengths of the triangle MNK given the angles, we need more information about the triangle. Specifically, we need either the lengths of two sides and one angle or the lengths of all three sides to fully determine the triangle.

Since we don't have the lengths of any sides in triangle MNK, we cannot calculate the side lengths directly. However, I can provide you with a general approach to solving triangles when you have enough information.

Let's assume the sides of triangle MNK are denoted as follows:

• MN (opposite to angle M) is denoted as m.
• NK (opposite to angle N) is denoted as n.
• KM (opposite to angle K) is denoted as k.

We have the following information for triangle MNK:

• Angle M = 80°
• Angle N = 60°

To find the side lengths, we need to use trigonometric ratios, such as the sine, cosine, or tangent, based on the given angles. However, without additional information about the triangle (e.g., another side length or an angle), we cannot proceed further.

If you have any additional information about triangle MNK, such as the length of one side or another angle, please provide it, and I'd be happy to help you find the side lengths. Otherwise, if you have a different question or need further assistance, feel free to ask!
