Question

В ромбе АВСД проведены диагонали. Угол АВС равен 18°. Найдите угол ВСД.

Answer 1

18+18=36 градусов, 360-36=324 градуса, 324/2=162 градуса.
Ответ:162 градуса.

Answer 2

Given Information:

We are given that a rhombus ABCD has diagonals AC and BD, and angle ABC is 18°. We need to find the measure of angle CDS.

Solution:

To find the measure of angle CDS, we can use the properties of a rhombus.

In a rhombus, the diagonals are perpendicular bisectors of each other. This means that angle ABC is equal to angle CDS.

Therefore, the measure of angle CDS is 18°.

Summary:

In a rhombus ABCD with diagonals AC and BD, if angle ABC is 18°, then angle CDS is also 18°.

Note: The sources provided do not directly answer the question, but the properties of a rhombus are well-known geometric properties.
