Answer 2

To solve the equation (4/5)^sin + (5/4)^sin = 2, you'll need to use some numerical methods or a calculator to approximate the solution because it involves trigonometric functions.

One way to approach this is by using a numerical solver or a graphing calculator. Here's a step-by-step approach using a graphing calculator:

1. Rewrite the equation as follows: (4/5)^sin + (5/4)^sin - 2 = 0

2. Graph the function f(x) = (4/5)^x + (5/4)^x - 2.

3. Use the calculator's root-finding feature to find the x-value where f(x) = 0.

The solution to the equation is approximately the x-value where the graph intersects the x-axis. Keep in mind that there might be multiple solutions, and you might need to adjust the viewing window on your calculator to find all of them.

Alternatively, you can use numerical methods like the Newton-Raphson method or bisection method on a computer program to approximate the solution.

Without a calculator or numerical solver, finding an exact analytical solution to this equation is quite challenging due to the transcendental nature of the equation involving sine.
