Why can't you have a shoe size of 4.5 and a height of 72 inches?

liq [111]

Answer:

Ok, lemme say something.

4.5 shoes are for 9 inch feet.

Dont think a 6 foot person is gonna fit tbh.

Step-by-step explanation:

A shoe size is for relation to feet size. Your feet grow from your height too, along with weight. If you are 6 feet, your feet are gonna be more than at least 1 foot.

4.5 shoes are for 9 inch feet

1 foot = 12 inches.

12 > 9.

12-9=3.

The two men measure the angle of elevation to the highest point on the rock to be 22.6°. They

IgorC [24]

Answer:

15 m

Step-by-step explanation:

<em>Refer to attached picture</em>

The height = h
Angles of elevation 22.6° and 38.3°
Closer distance = d

<u>Use tangent to solve</u>

tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)
tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79d

<u>Compare the equations above and find the value of d:</u>

0.42(d + 17) = 0.79d
0.42d + 7.14 = 0.79d
0.79d - 0.42d = 7.14
0.37 d = 7.14
d = 7.14/0.37
d = 19.3 m

<u>Now find the value of h:</u>

h = 0.79d
h = 0.79*19.3
h = 15
