<span>A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 64 are 1, 2, 4, 8, 16, 32, and 64. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The common factors are 1, 2, 4, and 8. Therefore, the greatest common factor is 8. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 64 are 2, 2, 2, 2, 2, and 2. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8. SummaryA factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.
Summary: The common factors of 64 and 72 are 1, 2, 4, and 8. The greatest common factor of 64 and 72 is 8.
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.
Step-by-step explanation:
The answer explains itself.
The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are <em>complementary</em> (not supplementary).
