Notice the little right triangle (5). The shaded angle is A, because the line on its top side is parallel to the base line. Similar right triangles with an angle A show that the top angle, marked A, also equals the original A. The top part of the opposite (6), over the longest of that shaded triangle, is cos A. The opposite over the main hypotenuse (7) is sin B. Since the side marked "opposite" (7) is in both the numerator and denominator when cos A and sin B are multiplied together, cos A sin B is the top part of the original opposite — for (A + B) — divided by the main hypotenuse (8).. As the examples showed, sometimes we need angles other than 0, 30, 45, 60, and 90 degrees. In this chapter you need to learn two things: 1. Sin(A + B) is not equal to sin A + sin B.. If A and A+B are acute angles so that sin(A+B)=24/25 and tan A=3/4 then find the value of cos B?.

A is reflex means A is in fourth quadrant . B is obtuse means B is in second quadrant. From pythagorean theorem. Since cot(A) is negitive on fourth quadrant .. Since cot(B) is negitive on second quadrant .. Apply compound angle formula. Sine Calculator. Trigonometric sine calculator. Sine calculator. In order to calculate sin(x) on the calculator: Enter the input angle. Select angle type of degrees (°) or radians (rad) in the combo box. Press the = button to calculate the result.. The problem as stated does not restrict x to the interval [0, π]. As far as I can tell, x can be any real number for which sinx = 24/25.. Upload failed.

I would start by drawing the triangle, inside the rectangle (remember that the altitude h is perpendicular to the base b).. First, you can say that the area of the rectangle is hb.Then you can reason that the triangle's area is ½hb since it neatly divides the rectangle into two pairs of congruent triangles.. Now look at the right triangle I've shaded..
