HELP ITS URGENT Find the value of x.

Mathematics
1 answer:
saul85 [17]3 years ago
7 0

Answer:

Step-by-step explanation:

Exterior angle property:

Exterior angle of a triangle equals the sum of  opposite interior angles

∠WBC = ∠D + ∠C

18x + 5 = 46 + 8x - 1

18x + 5  = 8x + 45  

Subtract 5 from both sides

18x = 8x + 45 -5

18x = 8x + 40

Subtract 8x from both sides

18x - 8x = 40

10x  = 40

Divide both sides by 10

x = 40/10

x = 4

Not sure why such an old question is showing up on my feed...

Anyway, let x=\tan^{-1}\dfrac43 and y=\sin^{-1}\dfrac35. Then we want to find the exact value of \cos(x-y).

Use the angle difference identity:

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

and right away we find \sin y=\dfrac35. By the Pythagorean theorem, we also find \cos y=\dfrac45. (Actually, this could potentially be negative, but let's assume all angles are in the first quadrant for convenience.)

Meanwhile, if \tan x=\dfrac43, then (by Pythagorean theorem) \sec x=\dfrac53, so \cos x=\dfrac35. And from this, \sin x=\dfrac45.

So,

\cos\left(\tan^{-1}\dfrac43-\sin^{-1}\dfrac35\right)=\dfrac35\cdot\dfrac45+\dfrac45\cdot\dfrac35=\dfrac{24}{25}

What is the surface area of the triangular prism?
Svetlanka [38]

Answer:

84

Step-by-step explanation:

Using pythag theorem we can find the last side of the triangle, which is equal to 5 after we have this we simply add up the areas of each individual shape like (1/2*3*4)+(1/2*3*4)+(6*5)+(3*6)+(4*6)
