Answer:
The height of the triangle is always the measurement of a line (often shown as dashes) that is perpendicular to the base and extends to the opposite angle at the top of the triangle.
If it is a right triangle, and the right angle is at the bottom, the side extending up from the right angle will be the height. But this is not always the case.
Answer:
The mean of this set of numbers is 12.5.
Step-by-step explanation:
first add all of the numbers, we get a product of 75, then divide by the number of numbers (6) and we get an answer of 12.5.
Hi there!
~
cosec 20 -cot 40= 1/sin 20 - cos 40/sin 40
= (sin 40 -cos 40 sin20)/(sin 40 sin 20)
= 1/sin 40 ( 2 cos 20 - cos 40)
=1/sin20 ( 2 cos(60-40)-cos 40)
=1/sin40( 2 cos 60 cos 40 - 2 sin 60 -sin 40-cos 40)
Put the value of cos 60
= 1/sin 40 ( 2 sin 60 sin 40)
=root(3)
Hope this helped you!
