While standing exactly halfway between two tall trees. nikki spots a blue jay at the top of one tree and a cardinal at the top of the other, as shown from nikki is pom‘t of view, the angles of elevation to the blue jay and to the cardinal are 60° and 50", respectively. the trees are 40 m apart.

The height of one trees is 34.64 meters

The height of other tree is 23.83 meters

Step-by-step explanation:

Given as :

The distance between two trees = d = 40 meters

Nikki is standing at the center O of two tress

The distance between center to one tree = OB = 20 meters

The distance between center to others tree = OD = 20 meters

The angle of elevation of one tree = 60°

The angle of elevation of other tree = 50°

Let The height of one tree = H meters

Let The height of other tree = h meters

Now, From figure

Tan angle =

Or, Tan 60°=

Or, 1.732 =  

∴  H = 20 × 1.732

i,e H = 34.64 meters

So, The height of one tree = H = 34.64 meters

Again

Tan 50°=

Or, 1.1917 =  

∴  h = 20 × 1.1917

i,e h = 23.83 meters

So, The height of other tree = h = 23.83 meters

Hence, The height of one trees is 34.64 meters and The height of other tree is 23.83 meters  Answer

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
