Pls help me with this problem:( and I’ll be happy if you write steps for this
andreev551 [17]

Answer:

b/(b+a)

Step-by-step explanation:

(1/a)-(1/b) :[ (b²-a²)/ab²]

first  solve :

common denominator ab

(1/a)-(1/b)  = (b-a)/ab

[b-a/ab] : [(b²-a²)/ab²]

when divide fraction ( division sign turn to (×) and flip the second fraction(reciprocal):

[b-a/ab] × [ab²/ (b²-a²)]

then  simplify : ab²/ab = b

(b-a)×(b/b²-a²)    

factorize : b²-a² = (b-a)(b+a)

(b-a)×(b/(b-a)(b+a))  simplify : (b-a)/b-a = 1

[(b-a)(b)]/[(b-a)(b+a)

b/b+a

Cos^4 (A/2)- sin^4(A/2)=cosA
pashok25 [27]

Answer:

LHS=cos^4(A/2)-sin^4(A/2)

={cos^2(A/2)}^2 -{sin^2(A/2)}^2

={cos^2(A/2) - sin^2(A/2)}{cos^2(A/2) +sin^2(A/2)}

=cosA×1

=cosA

Find the length of GV¯¯¯¯¯¯¯¯ A. 43.92 B. 33.1 C. 41.45 D. 68.87
ValentinkaMS [17]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find GV

To find GV we use cosine

cos∅ = adjacent / hypotenuse

From the question

GV is the adjacent

GC is the hypotenuse

So we have

<h3>\cos(37)  =  \frac{GV}{GC}</h3>

GC = 55°

<h3 /><h3>GV</h3><h3>\cos(37)  =  \frac{GV}{55}</h3><h3 />

GV = 55 cos 37

GV = 43.92495

We have the final answer as

<h3>GV = 43.92</h3>

Hope this helps you
