In the proof of the law of cosines, the equation c^2=h^2+(b-x)^2was created using the pythagorean theorem. which equation is a result of expanding (b-x)^2? a. c^2=h^2+b^2-x^2 b. c^2=h^2+b^2-2bx+x^2 c. c^2=h^2+b^2+x^2 not d two construction workers, tyrone and diego, are standing 15 yards apart, looking up at a piano hanging between the two men from a crane. tyrone is staring at the piano with an angle of elevation of 65°, and diego is looking up with an angle of elevation of 77°. what is the distance between tyrone and the piano? round the answer to the nearest tenth. 9.0 yd 16.1 yd 22.1 yd 23.7 yd

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

answer: 7. if the functions had a negative leading coefficient and is of even degree, which statement about the graph is true?
