Answer:

Anthony is incorrect

According to the order of operations(PEMDAS), you must first multiply 10 × 3

which equals 30, then you add 2, which equals 32, finally you subtract 2, which brings you back to 30

10 × 3 = 30

2 + 30 - 2 = 30

Using the Pythagorean theorem, if the hypotenuse is 17 feet long, and side a is 15 feet long. What is the missing length of side
Shtirlitz [24]

Answer:

The missing side is 8 ft long

Step-by-step explanation:

According to Pythagoras theorem <em> "It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides"</em>

mathematically it is stated as

c^2= a^2+b^2\\\\c=\sqrt{a^2+b^2}

Given that

c, hypotenuse= 17 ft

a = 15 ft

b= ?

Applying the Pythagoras theorem formula by inserting our given parameters and solving for b we have

17^2= 15^2+b^2

Making b subject of formula we have

b^2= 17^2-15^2\\\\b^2= 289-225\\\\b^2= 64\\\\

Square root both sides we have

b= \sqrt{64} \\\\b= 8

Hence the missing side is 8 ft long
