A 21 foot tower must be secured with a wire anchored 7 feet from the base of the tower. What angle will the wire make with the ground? Round your answer to the nearest tenth.

71.6

Step-by-step explanation:

opposite=height= 21 ft

Adjacent= length of shadow = 7ft

Angle of inclination= C

tan C = 21/7

C= tan‐¹(3)= 71.6

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
