Answer:

30 m

Step-by-step explanation:

Picture the question as a triangle

The length of the string is the hypotenuse, 60 m

The angle from the ground is 30

The right angle C is from the height of the kite to the ground

The missing angle A 60 is located on the top of the kite

now find b, the height

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(A)=adj/hyp

cos(A)=b/c

b=c*cos(A)

b=60*cos(60)

b=30

Does the system have one solution,no solution,or infinitly many? Use substitution to justify your answer
Bad White [126]

Answer:

(0,3) One solution

Step-by-step explanation:

Step: Solve x+5y=15for x:

x+5y=15

x+5y+−5y=15+−5y(Add -5y to both sides)

x=−5y+15

Step: Substitute −5y+15for x in 7x+2y=6:

7x+2y=6

7(−5y+15)+2y=6

−33y+105=6(Simplify both sides of the equation)

−33y+105+−105=6+−105(Add -105 to both sides)

−33y=−99

−33y

−33

=

−99

−33

(Divide both sides by -33)

y=3

Step: Substitute 3 for y in x=−5y+15:

x=−5y+15

x=(−5)(3)+15

x=0(Simplify both sides of the equation)

Therefore (0,3) which is one solution
