7/2x is ur answer since the denominator is the same so you just add the numerators together
Answer:
length = 62.41 inches
Step-by-step explanation:
Using pythagoras theorem -
Let
a = hypotenuse
b = height
c = length
a^2 = b^2 +c^2
75^2 = 41.6^2 + c^2
Therefore,
75^2 - 41.6^2 = c^2
5625 - 1730.56 = c^2
389.44 = c^2
square root (389.44) = c
62.40544848 = c
Answer:
Scalene and obtuse
Step-by-step explanation:
The triangle is scalene because all the sides are not equal, and it is obtuse because the central angle is greater than 90 degrees.
I'd help if I could, but unfortunately, this is the one area of math that I suck at.
Given the radius of the inscribed circle, the length of any side of the octagon (and any other polygon) is given by;
Side = 2r* tan (180/n) where r=radius and n=number of sides.
For octagon, n= 8 and radius is given by , r= 7/2 = 3.5 ft
Therefore,
Side = 2*3.5*tan (180/8) 2.8995 ft =2.9 ft.
The correct answer is A.
