Answer:

135.94 feet

Step-by-step explanation:

Split the problem into two parts :

Distance between viewer and building
Height of the top part of the building

Distance between viewer and building

The lower part of the building is 40 feet, as it is mentioned the viewer is 40 feet above street level
Let the distance be called 'd'
Therefore, tan37° = 40/d
tan37° = 3/4 = 0.75
⇒ 40/d = 0.75
⇒ d = 40/(3/4) = 40 x 4/3 = 160/3 = 53.3 feet

Height of the top part of the building

Let the height of the top part be 'h'
Therefore, tan61° = h/d = h/53.3
tan61° = 1.8
⇒ h/53.3 = 1.8
⇒ h = 53.3 x 1.8 = 95.94 feet

Total height of building

Lower part + Top part
40 + 95.94
135.94 feet

Kevin using 84 fluid ounces of water to make in all purpose cleaner. The directions call for 4 fluid ounces of concentrated soap

nata0808 [166]

He should use 886 fluid ounces of soap.

Step-by-step explanation:

Know that 8 fluid ounces make 1 cup.

Now 24 cups need 32 fluid ounces or, 3 fluid ounces of water need 32 fluid ounces of soap.

Thus, by unitary method,

84 ounces of water need 32 × 84 / 3 ounces of soap.

Thus the answer comes to 886 ounces.

If a=under root s(s-a)(s-b)(s-c) then the value of a, when a =3 b =4c = 5 and s =a+b+c by 2

kramer

Answer:

Step-by-step explanation:

Here it's given that ,

$\sf\red{\longrightarrow} A=\sqrt{s(s-a)(s-b)(s-c)}$

Also ,

$\sf\red{\longrightarrow} s =\dfrac{a+b+c}{2}$

And we need to find out the value of A , when

a = 3
b = 4
c = 5

So , on substituting the respective values to find s we have ,

$\sf\red{\longrightarrow} s =\dfrac{3+4+5}{2}=\dfrac{12}{2}=\bf{6}$

Now let's find out A as ,

$\sf\red{\longrightarrow} A = \sqrt{6(6-3)(6-4)(6-5)} \\$

$\sf\red{\longrightarrow}A =\sqrt{6 * 3 * 2 * 1}\\$

$\sf\red{\longrightarrow} A = \sqrt{3^2 * 2^2 *1^2}\\$

$\sf\red{\longrightarrow}A = 3*2\\$

$\sf\red{\longrightarrow}\boxed{\qquad \blue{\bf A = 6 \qquad}}$
