If 5 painters can paint 5 rooms in 5 days, how long will it take 10 painters to paint 10 rooms?
This problem involves understanding the rate of work. Since 5 painters can paint 5 rooms in 5 days, one painter can paint one room in the same amount of time. This is because the work is directly proportional to the number of workers and the time taken. Therefore, 10 painters can also paint 10 rooms in 5 days, as the
In a triangle, two angles measure 65° and 45°. What is the measure of the third angle, and why?
To solve this, use the fact that the sum of the angles in a triangle is always 180°. If two of the angles are 65° and 45°, then the third angle can be found by subtracting the sum of these two angles from 180°: 180° - (65° + 45°) = 180° - 110° = 70°. So, the measure of the third angle is 70°. This is because the sum
What's a right angle?
A right angle is an angle that measures exactly 90 degrees. It is one of the basic types of angles in geometry and represents a quarter turn or a perpendicular intersection of two lines. Right angles are often denoted by a small square placed in the angle's corner. They are a fundamental aspect of many geometric figur
What's an obtuse angle?
An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. It's larger than a right angle (which is exactly 90 degrees) but smaller than a straight angle (which is exactly 180 degrees). Obtuse angles are common in various geometric shapes and designs.
