gcf of 33 77 and 132
The GCF of 33, 77, and 132 is 11.
The GCF is 11.
Since 37 is a prime number, the GCF is 1
The GCF of 55, 77, and 132 is 11.It is 11
The Highest Common Factor (HCF) of 55, 77, and 132 is the largest number that divides all three numbers without leaving a remainder. To find the HCF, you can first find the prime factors of each number: 55 = 5 x 11, 77 = 7 x 11, and 132 = 2^2 x 3 x 11. Then, identify the common prime factors among the numbers, which are 11. Therefore, the HCF of 55, 77, and 132 is 11.
This can be solved using the cosine rule to find the length of side EF, and the sine rule to find angle E The cosine rule is: a² = b² + c² - 2bc cos A we have: A = G = 132° a = EF b = EG = 77 inches c = FG = 89 inches (the assignment of b and c doesn't matter as they are the two sides of the angle A and are interchangeable for the cosine rule), giving: EF² = 77² + 89² - 2×77×89×cos 132° → EF = √(77² + 89² - 2×77×89×cos 132°) The sine rule is: (sin A)/a = (sin B)/b = (sin C)/C we have: A = G = 132° a = EF = √(77² + 89² - 2×77×89×cos 132°) inches (found above) C = E c = FG = 89 inches → (sin 132°)/√(77² + 89² - 2×77×89×cos 132°) in = (sin E)/89 in → sin E = (89 sin 132°)/√(77² + 89² - 2×77×89×cos 132°) → E = arc sin((89 sin 132°)/√(77² + 89² - 2×77×89×cos 132°)) → E ≈ 25.8° → E ≈ 26° to the nearest degree
