Answer:
The length of EB is found 15
Step-by-step explanation:
As the diagram of the circle is not given in the question, I've found the diagram of the same question from internet and attached below. So that we can have a better understanding)
We can see in the diagram the chord AB and chord CD intersect each other at point E.
Each of the chord is divided into two segments.
According to the Intersecting Chords Theorem:
Products of the lengths of line segments on each chord are equal
Which means that
(AE)(EB) = (CE)(ED)
Substitute the given values;
(4)(EB) = (10)(6)
4(EB) = 60
EB = 15
The answer is 57.49°
57°29'38" = <span>57° + 29' + 38"
</span>
1° = 60'
x° = 29'
1 : 60 = x : 29
x = 29 * 1 : 60 = 0.48°
<u>29' = 0.48°</u>
1° = 3600''
x° = 38''
1 : 3600 = x : 38
x = 38 * 1 : 3600
x = 0.01°
<span><u>38'' = 0.01°</u>
</span>
57°29'38" = 57° + 29' + 38" = 57° + 0.48° + 0.01° = 57.49°
Answer:
tan(23° -21°) = (tan(23°) -tan(21°))/(1 +tan(23°)tan(21°))
Step-by-step explanation:
The formula for the tangent of the difference of angles is ...
tan(a-b) = (tan(a) -tan(b))/(1 +tan(a)tan(b))
Filling in the values a=23° and b=21°, you get the formula shown above.
Answer:
8/3
Step-by-step explanation:
a perpendicular lines slope will always be the opposite reciprocal of the original slope.
