We know that
in a right triangle
applying the Pythagoras theorem
c²=a²+b²----------> b²=c²-a²
where
c is the hypotenuse-------> c=8 yd
a and b are the legs of the triangle
a=6 yd
b=?
b²=c²-a²-----> b²=8²-6²-----> b²=64-36----> b²=28-----> b=√28---> 5.29 yd
the answer is
5.3 yd
C because 2,400 divided by 450 is a little more than 5 and 5 times 12 is 60 and a little more than 60 is 64.
Complementary angles are 90°
90° - 46° = 44°
Angle 4 is 44°
X+2x=63 3x=63 x=21 21*2 is 42 so long is 42 and 21 is short
Supplementary angles add up to 180 degrees.
so if one angle is 60 degrees, then the other angle is (180 - 60) = 120
