Answer:

x ≈ 61.3

Step-by-step explanation:

Using the Sine rule, that is

\frac{6}{sinx} = \frac{5.8}{sin58} ( cross- multiply )

5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )

sin x = \frac{6sin58}{5.8} ≈ 0.87729, thus

x = sin^{-1} (0.87729) ≈ 61.3

The difference of two numbers is 42. the larger number is three less than six times the smaller number. find the numbers.
IgorLugansk [536]
X and y are the numbers
x>y

diffference is 42
x-y=42

larger is 3 less than 6 times smaller
x=-3+6y

subsitute -3+6y for x

x-y=42
-3+6y-y=42
-3+5y=42
add3 to both sides
5y=45
divide both sides by 5
y=9

sub back

x=-3+6y
x=-3+6(9)
x=-3+54
x=51

the numbers are 51 and 9

<h3>Way to do</h3>

#since the x inside (x) change into (5), then just change the x with (5)

f(x) = 3x + 2

f(5) = 3(5) + 2

f(5) = 15 + 2

f(5) = 17
