Answer:

61.97 feets

Step-by-step explanation:

Using trigonometry :

Horizontal distance between the person and building,

Let distance = d

Tan 15 = 15 / d

0.2679491 * d = 15

d = 15 / 0.2679491

d = 55.980781

To obtain the height, h :

tan 40 = (h-15)/d

d = 55.98

h-15 = 55.98 (tan 40°)

h - 15 = 55.98 * 0.8390996

h - 15 = 46.972797

h = 46.972797 + 15

h = 61.972797

h = 61.97 feets

Which equation is equivalent to sqrt x +11=15
Bas_tet [7]

Answer:

x=16

Step-by-step explanation:

We are given that

\sqrtx+11=15

we have to solve this equation for x

in order to do that we need to isolate x first

hence

subtracting 11 from both sides we get

\sqrtx+11-11=15-11

\sqrtx=4

Now we square on both sides we get

(\sqrtx)^2=4^2

x=4 \times 4

x=16

hence x =16

Are they unique more than one or no triangle
Tanya [424]
The measures of the angles of a triangle add to 180.

45 + 45 + 90 = 180
The measures of these three angles do add to 180, ,so there is at least one triangle with these angle measures.
Using AA triangle similarity, any triangle with the same angle measures will be similar.

From the figure you already see two triangles with angles 45-45-90. There is an infinite number of triangles with those angle measures.

Choose all the numbers that are part of Integers.
Aleksandr [31]

Answer:

  all except 5/6

Step-by-step explanation:

All of the numbers listed are in the set of integers, except for the fraction 5/6. It is a rational number, but not an integer.

___

If by "part of integers" you mean that the number can be multiplied by some integer value to make an integer, then 5/6 is "part of 5". It is 1/6 of the integer 5.
