Construction workers planned to secure a tall pole using two cables attached to the pole at a point 12 meters above ground.

what is the total legth of the cable ?

please round to the nearest tenth

Theres a triangle inside theres a pole that measures 12 meters on one side of it in the inside there is 45 degree angle on the other side in the inside theres is a 30 degree angle.

it is a triangle

We need to know the angle of the wires to the ground or wires to the pole to figure this one ,,,,,

OK..... you have two RIGHT triangles

sine = opp / hypotenuse (this assumes the angles you gave me are the angles the cables make with the ground)

= 12/hyp

sine 30 = 12/hyp

.5 = 12/hyp hyp = 24 for one side

the OTHER side

sin 45 = 12/hyp hyp = 16.97 total = 24 + 16.97 = 40.97 m

Sorry ....I edited this several times !!
