Question

Начертили биссектрису ВК треугольника АВС С тупым углом в 140 ГРАДУСОВ.Угол В=140 градусов Найдите градусную меру углов АВК и СВК

Answer 1

Так как ВК биссектриса угла В, то ∠АВК=∠СВК=∠В:2=140:2=70°
Ответ:∠АВК=70°; ∠АВК=70°.

Answer 2

Bisector of Angle VK of Triangle ABC

To find the measure of angles AVK and CVK, we can start by calculating the measure of angle VKC. Then, we can use the properties of angles to find the measures of AVK and CVK.

Calculating Angle VKC

Given: Angle VKC = 140 degrees

Finding Angle AVK

To find the measure of angle AVK, we can use the property that the angles on a straight line add up to 180 degrees. Since VKC is 140 degrees, AVK can be calculated as: AVK = 180 - VKC

Finding Angle CVK

Similarly, to find the measure of angle CVK, we can use the property that the angles in a triangle add up to 180 degrees. Since VKC is 140 degrees, CVK can be calculated as: CVK = 180 - VKC

So, the measures of angles AVK and CVK can be calculated using the above formulas.
