Let the height of the first tower be x, then the second tower is (160 - x) m taller than the first tower. Then
tan 30 = (160 - x)/80
160 - x = 80 tan 30
x = 160 - 80 tan 30 = 160 - 46.19 = 113.8 m

Therefore, the height of the first tower is 113.8 m.

Point A is (5, 7).
spin [16.1K]

The coordinate of point B is at (29, -15): Option C is correct.

The formula for calculating the midpoint of two points is expressed as:

M(x, y) = {\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}}

Given the coordinate points

A is (5, 7).

B is (x, y).

M is (17, -4)

Substituting into the formula to get x and y

17 = 5+x/2

5+x = 34

x = 34 - 5

x = 29

Get the value of y. Similarly;

-4 = 7+y/2

-8 = 7+y

y = -8-7

y = -15

Hence the coordinate of point B is at (29, -15)

prisoha [69]

Answer:

Between 5 and 6

Step-by-step explanation:

Integers refer to positive whole numbers.

Firstly, we need to know the value of the surd

By calculating, the value of the surd is 5.29

What this mean is that the surd is between the values of 5 and 6

It is slightly greater than 5 and not up to 6
