No. For example, the angles of every equilateral triangle ... whether its sides
are 1 nanometer, 1 inch, 1 mile, or 1 light-year long ... are always 60 degrees
each. The angles alone may reveal the <u>ratios</u> of the sides, but they tell nothing
about the actual length of any of the sides.

Answer:

This is an example of placebo testing.

Step-by-step explanation:

This is an example of placebo testing in which, the two groups are given two substances that are said to have an effect on the condition that is being treated but one of them is the actual medicine that is being tested while the other one has no real effect over the medical condition.

stich3 [128]

Answer:

Step-by-step explanation:

given that a balloon is hovering 800 ft above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20 degrees. Twenty-five seconds later, the crew has to look at an angle of 65 degrees to see the balloon

The distance of the boat from the balloon measured horizontally in the I position = 800 tan 20

After 25 seconds distance of the boat from the balloon measured horizontally in the II position

= 800 tan 65

Distance moved by the boat in 25 seconds

= $800(tan 65-tan 20)\\= 1342.56$

Speed of the boat per second = $\frac{1342.56}{25} \\=53.702$

53.702 feet per second is the speed of boat
