Answer:
5/6 - 10/12, 15/18, 20/24
3/8 - 6/16, 9/24, 12/32
Step-by-step explanation:
Answer:
Hence r=10.3 cms (rounded to tenth place)
Step-by-step explanation:
In Triangle KLN ,
KN = 5 Cms
LN = ½ of LM
As the Perpendicular dropped from the center to the chord bisects it.
LM = 18 cm
LN = 9 cm
Now we have to find r or KL
We apply Hypotenuse Formula in this
The formula is given as
Where c = r
a=5
b=9
Putting them in the formula
Answer: X = 44.4 degrees
Step-by-step explanation: The figure given is a right angled triangle with two sides given as well as one angle unknown.
Angle X, which is the unknown, is the reference angle in this question. So we have an opposite which is the side facing the reference angle (line 7 units) and we have an hypotenuse which is the side facing the right angle (line 10). Having an opposite and an hypotenuse, we can use the trigonometric ratio of sine.
SinX = opposite/hypotenuse
SinX = 7/10
SinX = 0.7000
Looking up a table of values or checking the calculator, 0.7000 under sine of angles gives 44.4270
Therefore angle X is approximately 44.4 degrees (approximated to the nearest tenth)
728/4= 182
182 estimated is 199.
