Question

Побулуй 20% від прямого кута

Answer 1

Відповідь:

18°

Покрокове пояснення:

прямий кут = 90 °

90° - 100%

х - 20%

90*20/100= 18°

Answer 2

Ответ:

прямой угол =90⁰

90⁰=100%

х=20%

100х=90×20

100х=1800

х=1800÷100

х=18⁰

90÷100%×20%=0,9×20%=18⁰

Answer 3

20% of a right angle is equal to 18 degrees.

A right angle is defined as an angle that measures exactly 90 degrees. To calculate 20% of a right angle, we need to find 20% of 90 degrees.

To calculate 20% of a value, we can multiply the value by 0.2. In this case, we can multiply 90 degrees by 0.2 to find 20% of a right angle.

The calculation is as follows:

20% of 90 degrees = 90 degrees * 0.2 = 18 degrees.

Therefore, 20% of a right angle is equal to 18 degrees.
