It's geometry and it is asking me to find x angel with only the length of the hypotenuse which is 13 and the length of the adjacent which is 12 but i don't know how to put cos-1(12/13) in my calculator

%40

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
