3 x 3/4 x 3

4 9/12 - 1 1/3

1 x 4/3 x 4

4 9/12 - 1 4/12

A cable extends from the top of a radio tower to a point 360 feet from the base of the tower. If the
Neko [114]

Step-by-step explanation:

we have a right-angled triangle :

the Hypotenuse (baseline opposite of the 90° angle) is the 850 ft cable from the top of the tower down to the point on the ground 360 ft away from the tower.

then the ground distance (360 ft) and the height of the tower are the 2 legs.

so, we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse.

in our case

850² = 360² + height²

height² = 850² - 360² = 592,900

height = 770 ft

the tower is 770 ft tall.

What must be true for lines a and b to be parallel lines? Select two options.
Rasek [7]

The expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10

<h3>Lines and angles</h3>

A line is the shortest distance between two points and the point where two lines meet is known as an angle

From the figure shown

m<2 = 58 degrees (alternate exterior angle)

Since the sum of angles on a straight line is 180 degrees, hence;

3x-1+<2 + 4x - 10= 180

3x-1 + 58 + 4x - 10 =180

7x + 47 = 180

7x = 180- 47

7x = 133

x = 19

Hence the expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10

jarptica [38.1K]

Step-by-step explanation:

circle=6

square=9

circle =10

square=? or x

ratio

6:10::9:x

product of mean =product of extreme

6x =9×10

6x=90

x=90/6

x=15

so there will be 15 square
