This is all about right triangles, assuming the tower is not the leaning tower of pisa! The tower is our height of the right triangle, the base of our triangle is the distance Nadia is from the tower, and the reference angle is 30 (the base angle that is NOT the right angle). The tower is opposite this reference angle, and the side 60 is adjacent to this angle, so we will use the tangent ratio, the trig identity that relates the side opposite the reference angle to the side adjacent to it.
. Solving for x we get x = 60 tan(30°). On our calculators that gives us that x = 34.64. That's how tall the tower is.
The answer is 28/5, just make it a fraction for both of them then subtract
All of the centra angles in a regular polygon must add up to 360 degrees. Also, because you're told that it is a regular polygon, the "regular" indicates that all of the central angles will be the same. Divide 360 degrees by 18 degrees to get the number of central angles, which is the same as the number of sides. 360/18 = 20. Therefore, the polygon has 20 sides. Hope that helps!
Answer:
An ostrich egg is 4 pounds, therefore, an ostrich egg is not greater than 5 pounds.
Step-by-step explanation:
Convert the ounces to pound.
1 pound = 16 ounces
Next, divide.
64 ÷ 16 = 4.
4 < 5
So, an ostrich isn't greater than 5 pounds
Have a wonderful day!
Factor an 8 out of both numbers: You're left with 5 and 12. The two numbers are relatively prime so we cannot factor any more out of both numbers.
Thus 8 is our greatest common factor.
