Question

У трикутнику АВС кут А дорівнює 60, кут С дорівнює 70. Знайдіть градусну міру кута В.

Answer 1

Ответ:

В=180-(60+70) =50

Ответ: В=50

Answer 2

Finding the Measure of Angle B in Triangle ABC

To find the measure of angle B in triangle ABC, we can use the fact that the sum of the angles in a triangle is always 180 degrees

Given that angle A is 60 degrees and angle C is 70 degrees, we can calculate the measure of angle B as follows:

Step 1: Find the sum of angles A and C: 60 + 70 = 130 degrees.

Step 2: Subtract the sum of angles A and C from 180 degrees to find the measure of angle B: 180 - 130 = 50 degrees.

Therefore, the measure of angle B in triangle ABC is 50 degrees.
