Solve for height using the tangent method. Show your work.

Murljashka [212]

Answer:

b = 17.318 height = 23.318 ft

Step-by-step explanation:

This IS very similar to the other one, Emily..... Have you tried to solve it the same way?

b = 152 tan 6.5 = 17.318 ft (using a calculator)

add the height of the victim's head (6 ft)

17.318 + 6 = 23.318 ft

PLEASE HELP I have been trying to figure this out for a really long time and I want to get the best grade on my test !

Shalnov [3]

Answer:

see below

Step-by-step explanation:

$-4^{2} =-16\\\\-\sqrt{4} =-2\\\\\sqrt{4^{2} } =4\\\\-2\sqrt{4} =-4\\\\(-4)^{2} =16\\\\\sqrt{1/4} =1/2$

so the order

-16

-4

-2

1/2

in root forms and exponent

$-4^{2} \\\\-2\sqrt{4} \\\\-\sqrt{4} \\\\\sqrt{\frac{1}{4} } \\\\\sqrt{4^{2} } \\\\(-4 )^{2}$
