Answer:
d
Step-by-step explanation:
The triangles are similar, thus the ratios of corresponding sides are equal, that is
= 
= 
( cross- multiply )
5(2x + 1) = 8(x + 4) ← distribute parenthesis on both sides )
10x + 5 = 8x + 32 ( subtract 8x from both sides )
2x + 5 = 32 ( subtract 5 from both sides )
2x = 27 ( divide both sides by 2 )
x = 13.5 → d
The three inside angles of a triangle when added together = 180 degrees.
Since two angles are given as 60 degrees, we know the third angle = 180 - 60 - 60 = 60 degrees.
When all three angles of a triangle are the same, it is an equilateral triangle and this means all three sides are also the same length.
This means the distance between each buoy is identical.
Answer:
12/100
Step-by-step explanation:
The surface area of a cylinder is given by
which is the surface area of cylinder A.
To compute the surface area of cylinder B, we have to map 
and we have the following formula
If we manipulate the second expression, we have
Which implies
