Question

The roof rafter of a house has been raised to a height of 13 yards at the ridge. Half of the length of the run measures 9 yards. Find
the length of the rafter. Round to the nearest 100th.

Answer 1

Answer:

Using Pythagorean theorem:- $a^{2} +b^{2} =c^{2}$

a= 13

b= 9

c= ? ( length)

$13^{2} +9^{2} =?^{2}$

$13^{2} =169$

$9^{2} =81$

$169+81=?^{2}$

$250=?^{2}$

$\sqrt{250}=15.811$

$?=15.81$

Answer 2

Answer:

15.81 = ?

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

9^2 + 13^2 = ?^2

81 +169 = ?^2

250 = ?^2

Taking the square root of each side

sqrt(250) =?

15.8113883= ?

To the nearest 100th

15.81 = ?
