Answer:
L is not valid.
Step-by-step explanation:
For any triangle, the sum of the two legs must be greater than the hypotenuse. Otherwise the two legs would not be long enough to touch.
Answer:
The radius of the duct is or
Step-by-step explanation:
The picture of the question in the attached figure
we know that
At the point of tangency, the tangent to a circle and the radius are perpendicular lines
so
In the right triangle formed
Applying the Pythagorean Theorem
Remember that
substitute
solve for r
Multiply by 16 both sides
convert to mixed number
----> exact value
The approximate value is
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
Answer:
in mathematics, the sine is a trigonometric function of an angle.
Step-by-step explanation:
The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
