Answer:
sinA = h/c; sinC = h/a
Step-by-step explanation:
Which pair of equations below is a result of constructing the altitude, h, in Triangle ABC?
sinA= h/c
sinC= h/a
sinA= h/c
sinB= b/c
sinA= b/c
sinC= b/a
Solution:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. From Pythagoras theorem, the square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.
In right triangle, trigonometric identities are used to show the relationship between the sides of a triangle and the angles.
sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite / adjacent
Therefore in triangle ABC:
sinA = h/c; sinC = h/a
Answer:
Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
Step-by-step explanation:
Given that a very large number of college men were asked what they thought their ideal weight was.
A five number summary of the response (in pounds) follows:
Median 175
Quartiles 155 196
Extremes 123 225
This implies that 25th percentile is 155 and 75th percentile is 196
This can be interpreted as approximately 50% of men lie between 155 and 196 pounds.
Since 195 is very near to 195, we can say approximately
i.e. 41 difference = 50%
40 difference =
Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
