Gala2k [10]

Answer:

3 : 5, 4: 5

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore, lengths of the legs of right triangle would be 3x and 4x

By Pythagoras Theorem:

{hyp}^{2}  =  {(3x)}^{2}  +  {(4x)}^{2}   \\  = 9 {x}^{2}  + 16 {x}^{2}  \\  = 25 {x}^{2}  \\  hyp =  \sqrt{25 {x}^{2} }  \\ hyp = 5x \\  \\ ratios \:  of each \:  leg  \: to  \: the \:  hypotenuse \\  \frac{3x}{5x}  = 3  : 5 \\  \\  \frac{4x}{5x}  = 4 : 5

In the figure shown, suppose m angle ABC=n and m angle ABD=2(m angle DBC). The angle bisector of angle DBC is BE. What is m angl
Yanka [14]

Answer:

n/6

Step-by-step explanation:

If angle bisector of angle DBC is BE. What is m angle EBC, then <DBE = <EBC

Since <ABC = <ABD+<DBC

n = 2<DBC+<DBC

n = 3<DBC

<DBC = n/3

Since <DBC = 2EBC

n/3 = 2<EBC

n/6 = <EBC

Hence <EBC = n/6
