Triangle abc is a right triangle if side ac=7 and bc=10 whats the measure of side ab

Mathematics

trapecia [35]3 years ago

If ab is the hypotenuse (the longest side)
a^2 + b^2 = c^2....a and b are the legs and c is the hypotenuse
7^2 + 10^2 = c^2
49 + 100 = c^2
149 = c^2...now take sq rt of both sides....this gets rid of the ^2
sq rt 149 = c
12.21 = c

if ab is a leg
a^2 + b^2 = c^2
7^2 + b^2 = 10^2
49 + b^2 = 100
b^2 = 100 - 49
b^2 = 51
b = sq rt 51
b = 7.14

The lengths of the legs of a right triangle are consecutive even integers. The hypotenuse is 58 inches. What is the sum of the l
miskamm [114]

Answer:

82 inches

Step-by-step explanation:

The difference between consecutive even integers is 2, thus

let the legs be n and n + 2

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

n² + (n + 2)² = 58² ← expand and simplify left side

n² + n² + 4n + 4 = 3364 ( subtract 3364 from both sides )

2n² + 4n - 3360 = 0 ( divide all terms by 2 )

n² + 2n - 1680 = 0 ← in standard form

(n + 42)(n - 40) = 0 ← in factored form

Equate each factor to zero and solve for n

n + 42 = 0 ⇒ n = - 42

n - 40 = 0 ⇒ n = 40

But n > 0 ⇒ n = 40

and n + 2 = 40 + 2 = 42

Thus sum of legs = 40 + 42 = 82 inches
