Answer:
(a). 
; (b). <em>33 to 40 </em>
Step-by-step explanation:
Use "magic fraction" 
<em>(a).</em> Distance covered by runner is 33 yards
Whole distance is 40 yards
The portion of the race that the runner has completed is
<em>(b).</em> The portion of the race that the runner has completed is <em>33 to 40</em>
Answer:
y = root under 24 (evaluate it if necessary)
or y = 2 root 6
Step-by-step explanation:
Let the reference angle be x
for the triangle in left,
b = 6-4 = 2
Now,
taking x as refrence angle,
cosx = b/h
or, cosx = 2/h
again,
for the bigger triangle,
taking x as reference angle,
cosx = b/h
or, cosx = b/6
As we can see base of bigger triangle is equal to hypotenuse of triangle at the left,
Let's suppose its a
so, cosx = a/6 = 2/a
now,
a/6 = 2/a
or, a² = 12
now,
for bigger triangle, using pythagoras theorem,
h² = p²+b²
or, 6² = y² + a²
or, 36 = y² + 12
or, y² = 24
so, y = root under 24
