Question

На прямой AB взята точка M. Луч MD – биссектриса угла CMB. Известно, что ∠DMC=48∘. Найдите угол CMA. Ответ дайте в градусах.

Answer 1

Я думаю так: раз DMC=48,то и угол CMВ=96(так как МD это биссектриса и делит угол пополам ) угол CMA= 180-96=84° Ответ: 84°

Answer 2

Problem Analysis

We are given a line segment AB and a point M on that line segment. The ray MD is the angle bisector of angle CMB, and we know that angle DMC is 48 degrees. We need to find the measure of angle CMA in degrees.

Solution

To find the measure of angle CMA, we can use the fact that the ray MD is the angle bisector of angle CMB. This means that angles DMC and CMA are equal in measure.

Given that angle DMC is 48 degrees, we can conclude that angle CMA is also 48 degrees.

Therefore, the measure of angle CMA is 48 degrees.
