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

Convert the following angle from degrees, minutes and seconds into decimal degrees. 27° 20' 58"

IRISSAK [1]

Answer:

27° = no answer or stays the same (not to sure on this one)

20' = 0.3°

58" = 0.0161°

Step-by-step explanation:

A minute = 1/60

A second = 1/3600

0 + 0 x 1/60 + 58 x 1/3600

1. white socks to brown socks

Semenov [28]

8 White
6 Black
4 Blue
5 Brown
Total=8+6+4+5=23

1. White to brown = 8:5
2. Blue to non-blue =4:(23-4) = 4:19
3. Black to all = 6 : 23
4. Ratios equivalent to Q1, 8:5
Multiply ratio by integer factors:
2(8:5)=16:10
3(8:5)=24:15
4(8:5)=32:20
etc.

Rectangle ABCD is shown with diagonal AC drawn. Point F is on AC and point E on DC such that FE is perpendicular to DC. Prove tr

777dan777 [17]

Triangle ABC is similar to triangle CEF.

Explanation:

Diagram is inserted for the reference.

ABCD is a rectangle.

ABC is a right angled triangle because all the angles of the rectangle are 90◦ - (a)

CEF is a right angled triangle because FE is perpendicular to DC – (b)

In triangles ABC and CEF,

1. Angle ABC = Angle CEF = 90◦ (Both are right angles from a and b)

2. Angle BCA = Angle EFC (Alternate angles on parallel lines are equal on intersection)

Hence using Similarity property of AA (Angle, Angle), Triangle ABC and CEF are similar.
