a) The triangle △ ABC is right-angled with right angle at corner C and angle α at corner A. Calculate a = | BC |, given that c = | AB | = 8, and that tan α = 12.

Calculate a= ?

b) In the triangle △ ABC before the designations a = | BC |, b = | CA |, c = | AB |, and ∠A = α, ∠B = β and ∠C = γ.
Find c, given that the triangle has an obtuse angle at C and that a = 1, b = 9 and sin γ = 58.
calculate c =?

Expert Solution

If you have any doubt in the solution please ask me im comments....

Here it is impossible to have sin is 58 so i assume that is 0.58.......

(1 point) Let θ(in radians) be an acute angle in a right triangle and let xx and yy, respectively, be the lengths of the sides adjacent to and opposite θ. Suppose also that x and y vary with time. At a certain instant x=8 units and is increasing at 1 unit/s, while y=5 and is decreasing at 1/3 units/s. How fast is θ changing at that instant?

Write in c++ as simple as possible In a right triangle, the square of the length on one side is equal to the sum of the squares of the lengths of the other two sides. Write a program that prompts the user to enter the length of three sides of the tringle (as doubles) and the outputs a message indication whether the triangle is a right triangle. You should split this into two functions (but only one .cpp file). One function is main()...
