Answer:

C. 40 ft

Step-by-step explanation:

First you need to set up the abc

a²+b²=C²

plug in the numbers

36²+18²= C²

you need to square both of the number than add them together

1296 + 324 = 1620

Than you need to square root the answer you just got

√1620

Which equals

40.24

But then round it to the nearest foot

So just 40

What is the value of cose in the diagram below?

Nuetrik [128]

Answer:

$cos \theta = 0.6$

Step-by-step explanation:

Draw a line from point ( 0.6, 0.8 ) to the X - axis, forming a right triangle with hypotenuse = r = 1 , adjacent = 0.6, opposite = 0.8

$cos \theta = \frac{adjacent}{hypotenuse} , \ where \ adjacent = 0.6 ,\ hypotenuse \ = r= 1$

$cos \theta = \frac{0.6}{1}\\\\cos \theta = 0.6\\\\\theta = cos^{-1} \ 0.6\\\\\theta = 53.13^\circ$
