Find the missing angle by subtracting the sum of the two angles from 180. Express the answer in degrees. Use the sine rule if given only one angle and two lengths of a triangle. The formula is sin A/a = sin B/b, where “A” and “B” are angles and “a” and “b” are the...
In the triangle above we are going to calculate the angle theta. Let x = 3, y = 4. Then by the Pythagorean theorem we know that r = 5, since sqrt(32+ 42) = 5. Now we can calculate the angle theta in three different ways. sin(theta) = y/r = 3/5 cos(theta) = x/r = ...

opposite to the angle to the length of the hypotenuse in a right triangle. To find the sine of 15 degrees, we can draw a right triangle with one of the angles as 15 degrees. Using basic trigonometric ratios, sine theta = opposite side/hypotenuse. For a 15 degree angle, the opposite si...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flo
