A 30 meter long cable is used to support a telephone pole, holding it perpendicular to the ground. If the cable forms a 60 °
angle with the ground, how far away from the base of the pole does the cable reach the ground?

A.
30
√
2
meters

B.
15 meters

C.
15
√
3
meters

D.
30
√
3
meters

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

it is x=-4

step-by-step explanation:

answer is because 4×10=40

and 98×4= is 392

40,392
