Adjacent side to angle 60º=2/3
opposite side to angle 60º=b
hypotenuse=a
cos 60º= adjacent side / hypotenuse
cos 60º=(2/3) / a
a=(2/3) / cos 60º=(2/3) / (1/2)=4/3
tan 60º= opposite side / adjacent side
tan 60º=b / (2/3)
b=(2/3)*tan 60º=(2/3)* √3=2√3 /3
Answer:
a=4/3
b=2√3 /3
The only ones that are functions are the ones where the y-coordinate does not repeat. B and D
4.25x + 7 = 53.75
Subtract 7 from both sides:
4.25x = 46.75
Divide both sides by 4.25:
X = 46.75 / 4.25
x = 11
69 plus 13 because 30 plus 13 is 43, 43 plus 13 is 56, and you know the rest
The answer is <span>length = 10 yd, width = 2 yd
proof
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20</span>
