Blacks and mulattos made up at least 19.3 % of the population of Santa Barbara. 1790. Blacks and mulattos constituted nearly 15% of the total San Francisco population and 18.5% of the settlers in Monterey. The population of Baja California included 844 Spanish-speaking persons of whom 183 were mulattos.
The same as the sum of angles of any quadrilateral. The sum of the angles only depends on the number of angles. If you want to visualize the sum of angles of a parallelogram, just draw one out and notice that there are two pairs of complementary angles, so the sum of the angles must be 360â.
From one of the vertices drop a perpendicular to the opposite side dividing that side in two lengths each of length 1 unit. The perpendicular is of length sqrt{2^2 - 1^2} = sqrt{4-1} = sqrt{3} The perpendicular bisector divides the 60 degree angle into two equal angles each of 30 degrees.We now have a triangle of 30, 60, 90 degrees with corresponding opposite sides of 1 unit, sqrt{3} units, 2 units respectively.he hypotenuse will in such a case be sqrt{1^2 + 1^2} = sqrt{1+1} = sqrt{2}. Sine(45) = Opposite Side/Hypotenuse = 1/[sqrt(2)] Cosine(45) = Adjacent Side/Hypotenuse = 1/[sqrt(2)] Tangent(45) = Opposite Side/Hypotenuse = 1/1 = 1 As regards the 30 and 60 degrees: Consider an equilateral triangle of side 2 unit each side.
