I need yo help B, on dis question

Anna71 [15]

For this case we can use the law of the sine to solve the problem.
We have then:
$5 / sine (68) = 5 / sine (x)
$
From here, we clear the value of x.
We have then:
$sine (x) = (5/5) * (sine (68))
$
Rewriting we have:
$sine (x) = (1) * (sine (68))

sine (x) = sine (68)

x = arcsine (sine (68))

x = 68$
Answer:
The angle R is given by:
x = 68 degrees

If f(x)= 9x-8 and g(x)=x^3,what is (g o f)(1)?

lesya692 [45]

(f∘g)(3) = f(g(3))

Find g(3) by substituting x=3 in g(x)

g(x)=x²-1

g(3)=3²-1

g(3)=9-1

g(3)=8

f*g(3) = f(g(3)) = f(8)

find f(8) by substituting x=8 in f(x):

f(x)=2x+3

f(8)=2(8)+3

f(8)=16+3

f(8)=19

So f∘g(3) = 19

Sorry I am wrong

20 POINTS! You are planning to use a ceramic tile design in your new bathroom. The tiles are equilateral triangles. You decide t

Answer:

210.33 cm^2

Step-by-step explanation:

We know that 6 equilateral triangles makes one hexagon.

Also, an equilateral triangle has all its sides equal.

If the tile of each side of the triangular tile measure 9 cm, then the height of the triangular tiles can be gotten using Pythagoras's Theorem.

The triangle formed by each tile can be split along its height, into two right angle triangles with base (adjacent) 4.5 cm and slant side (hypotenuse) of 9 cm. The height (opposite) is calculated as,

From Pythagoras's theorem,

$hyp^{2} = adj^{2} + opp^{2}$
