Nadya [2.5K]

Answer:

x = 3.67

Step-by-step explanation:

Simplify both expressions

14x - 18 = 5x + 15

Subtract the bigger (n)x by the smaller

14x - 5x = 9x

Plus the smallest by itself, giving you:

9x - 18 = 15

+18 +18

9x = 33

Simplify ( divided by 3 )

3x = 11

x = 3.67

To measure the height of a tree, a surveyor walked a short distance from the tree and found the angle of elevation was 43.9°, th

padilas [110]

Answer:

The height of the tree is H = 77.06 m

Step-by-step explanation:

From Δ ABC

AB = height of the tree

$\tan 43.9 = \frac{AB}{BC}$

$\tan 43.9 = \frac{h}{x}$

h = 0.9623 x ------- (1)

From Δ ABD

$\tan 37.6 = \frac{h}{20+ x}$

h = 0.77 (x + 20) ----- (2)

Equating Equation 1 & 2 we get

0.9623 x = 0.77 (x + 20)

0.9623 x = 0.77 x + 15.4

x (0.1923) = 15.4

x = 80.08 m

Thus the height of the tree is given by

H = 0.9623 x

H = 0.9623 × 80.08

H = 77.06 m

Therefore the height of the tree is H = 77.06 m
