Answer:
Jane's height is <u>63 inches</u>.
Step-by-step explanation:
Given:
Jane has her height measured using a metric ruler as 1.6 meters. She would like to know her height in inches. She knows that there are 100 centimeters in a meter and 2.54 centimeters in an inch.
Now, to find jane's height to the nearest inch.
The height of Jane measured using metric ruler = 1.6 meters.
As, 1 meter = 100 centimeters.
So, by using conversion factor we convert the height of Jane into centimeters from meters:
<em>Height of Jane in centimeters = 160.</em>
As given, 2.54 centimeters in an inch.
Now, we convert the centimeters by using unitary method:
If, 2.54 centimeters = 1 inch.
Then, 1 centimeters =
So, 160 centimeters =
<em>Thus, the height nearest to inch = 63 inches.</em>
Therefore, Jane's height is 63 inches.
Answers: sin(2∅) = 120/169, cos(2∅) = 119/169, tan(2∅) = 120/119
<h3>What are trigonometric functions?</h3>Trigonometric functions are used to establish the relationship between the sides and the angles of a right angle triangle.
Analysis:
If cos∅ = adjacent/hypotenuse = 12/13,
Then, opposite of the right angled triangle = = 5
sin∅ = 5/13, cos∅ = 12/13, tan∅ = 5/12
sin(2∅) = 2sin∅cos∅ = 2(5/13)(12/13) = 120/169
cos(2∅) = ∅ -
∅ =
-
= 144/169 - 25/169 = 119/169
tan(2∅) = sin(2∅) / cos(2∅) = 120/169 ÷ 119/169 = 120/119
