Answer 1

Ответ:1) 116 тупоугольный

2)113 тупоугольный

3) 90 прямоугольный

Пошаговое объяснение:

1) 180-64=116

2) 180-67=113

3) 180-90=90

Answer 2

Finding the Third Angle of a Triangle and Determining its Type

To find the third angle of a triangle and determine its type, we need to consider the given angles. Let's analyze each option:

1) 44° and 20°: To find the third angle, we can subtract the sum of the given angles from 180°. Therefore, the third angle would be:

Third angle = 180° - (44° + 20°) = 180° - 64° = 116°

The triangle with angles measuring 44°, 20°, and 116° is an obtuse triangle because one of its angles is greater than 90°.

2) 21° and 46°: Using the same method as above, the third angle would be:

Third angle = 180° - (21° + 46°) = 180° - 67° = 113°

The triangle with angles measuring 21°, 46°, and 113° is an obtuse triangle.

3) 28° and 62°: Again, applying the same calculation, the third angle would be:

Third angle = 180° - (28° + 62°) = 180° - 90° = 90°

The triangle with angles measuring 28°, 62°, and 90° is a right triangle because one of its angles is exactly 90°.

Therefore, the answer is: - For option 1, the third angle is 116°, and the triangle is an obtuse triangle. - For option 2, the third angle is 113°, and the triangle is an obtuse triangle. - For option 3, the third angle is 90°, and the triangle is a right triangle.
