Step-by-step explanation:

the solution to the equation 3.57x + 1.61 = 4.71 minus 2.63 x is x = 0.5.

He verifies his solution using the steps below. Equation:

3.57 x + 1.61 = 4.71 minus 2.63x

Step 1: 3.57 (0.5) + 1.61 = 4.71 minus 2.63 (0.5)

Step 2: 1.785 + 1.61 = 4.71 minus 1.315

Step 3: 3.395 = 6.025

Looking at step 2, 4.71 minus 1.315 = 3.395. This would make the left hand side of the equation and the right hand side of the equation to be the same. Therefore,

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
