Answer:
b=4.9
C. is the correct option.
Step-by-step explanation:
In triangle TGN,
Let <RTG be x
cosx= b/h
or, cosx = 2/a
Again,
In triangle TRG,
cosx = b/h
(for bigger right angled triangle)
cosx = a/(4+2)
cosx = a/6
Now
cosx = 2/a = a/6
or, 2/a = a/6
or, 12 = a²
so, a² = 12
Now,
For TRG,
h² = p²+b²
or, 6² = b² + a²(a²=12)
or, 6² = b² + 12
or, 36 = b² + 12
or, 36 -12 = b²
or, b² = 24
or, b = square root 24
so, b = 4.8989
so, b = 4.9
Answer:
the top answer
Step-by-step explanation:
right hand Riemanns are an over approximation, so it would include higher number sets.
The area for rectangle is (l x w) or (length times width) or (length x width)
*just in case you get confused
so the length is 10, and the width is 2.5 so you plug in.
10 x 2.5 = 25
your answer is 25 mm²

Answer:
2 2/3
Step-by-step explanation:
8/3= 2 2/3
Find out how many times 3 goes into 8.
3 goes into 8: 2 times
Because
3x2=6
8-6=2
Then you keep the Denominator, 8.
