Answer:
The value of x = √6/2
Step-by-step explanation:
Given
The hypotenuse of triangle = √2
Ф = 30°
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 30°
Adjacent to 30° = x
hypotenuse = √2
so substituting
cos Ф = adjacent / hypotenuse
cos 30° = x / √2
x = √2 × cos 30°
x = √2 × √3 / 2
x = √6/2
Therefore, the value of x = √6/2
Answer:
b. 189 square feet
18 X 12 = 216 square feet
4.5 X 3 = 13.5
13.5 X 2 = 27
216 - 27 = 189 square feet
Answer: 7
Step-by-step explanation:
You are given that Bill bought 38 1/2 feet of wire. Convert the mixed fraction into improper fraction.
The length L1 = 77/2
You are given that he cut the wire into several pieces, each one measuring 5 1/2 feet. Convert it too to improper fraction.
The length L2 = 11/2
To know how many number of pieces of wire he have after making the cuts, divide length L1 by length L2. That is,
L1/L2 = 77/2 ÷ 11/2
Change the division to multiplication by reciprocating 11/2 to 2/11
77/2 × 2/11 = 77/11 = 7
Therefore, he had 7 pieces of wires after making the cuts.
