Find A and B if sin2xcos3x = A sin 5x + B sin x
patriot [66]
Recall that

\sin(x+y)=\sin x\cos y+\cos x\sin y
\sin(x-y)=\sin x\cos y-\cos x\sin y

Adding these together, you have

\sin(x+y)+\sin(x-y)=2\sin x\cos y
\dfrac12\sin(x+y)+\dfrac12\sin(x-y)=\sin x\cos y

Replace x with 2x and y with 3x. You end up with

\dfrac12\sin(2x+3x)+\dfrac12\sin(2x-3x)=\sin2x\cos3x
\sin2x\cos3x=\dfrac12\sin5x+\dfrac12\sin(-x)=\dfrac12\sin5x-\dfrac12\sin x

and so A=\dfrac12 and B=-\dfrac12.

I need help in this question
dimulka [17.4K]

Answer:

x = 4

m∠EFH = 21°

m∠EFG = 83°

Step-by-step explanation:

We know that m∠EFH + m∠HFG will be equal to m∠EFG.

Since we know the values of each, we can make the equation:

5x + 1 + 62 = 18x + 11

Let's solve for x by isolating it on one side.

Combine like terms:

5x + 63 = 18x + 11

Subtract 11 from both sides:

5x + 52 = 18x

Subtract 5x from both sides:

52 = 13x

Divide both sides by 13:

x = 4

Now that we know the value of x, we can substitute it inside the formulas for m∠EFH and m∠EFG.

m∠EFH:

5x+1\\\\5(4)+1\\\\20+1\\\\21

m∠EFG:

18x+11\\\\18(4)+11\\\\72+11\\\\83

Hope this helped!

Question 1 on my integrated geometry test
NemiM [27]

Answer:

B. 15 cm

Step-by-step explanation:

Hypotenuse (h) = 17 cm

perpendicular (p) = 8 cm

base (b) = YZ = ?

We know that by using Pythagoras theorem

b = √ (h² - p²)

= √ ( 17² - 8²)

= √225

= 15 cm

YZ = 15 cm

Hope it will help :)❤
