Answer:

Use the SINE RULE:

$\frac{a}{ \sin( \alpha ) } = \frac{b}{ \sin( \beta ) }$

$\frac{6}{ \sin(60) } = \frac{x}{ \sin(90) }$

$x = \sin(90) \times \frac{6}{ \sin(60) }$

$x = 6.93$

(a) An angle measures 86 degrees . What is the measure of its supplement?

Molodets [167]

Answer:

The supplement is 94

Step-by-step explanation:

Supplementary angles add to 180 degrees

x+86 = 180

Subtract 86 from each side

x+86-86 =180-86

x = 94

Solve for x.

olga nikolaevna [1]

Answer:

$\boxed{x=5},x=-9$

Step-by-step explanation:

To rid the denominators, multiply both sides by $(x-3)(x+1)$ .

We get:

$6(x+1)-12(x-3)=(x-3)(x+1)$

Simplifying, we have:

$6x+6-12x+36=x^2-3x+x-3,\\-6x+42=x^2-2x-3,\\x^2+4x-45=0$

Solving, we get:

$x^2+4x-45=0,\\(x-5)(x+9)=0,\\x=5,x=-9$

Therefore, the solution with the greatest value is $x=\boxed{5}$

Please Help). Use the figure below to answer the questions. A) Describe in words a sequenc of transformations that maps □ABC to

lesya [120]

Answer:

See below

Step-by-step explanation:

The initial ordered-pairs are $(x, y)$

We have a rotation of 90 degrees counterclockwise with respect to origin

Note. Previously the points were

$A(-3, 4), B(-3, 0), C(-1, 3)$

After the rotation, we have

$A(-4, -3), B(0, -3), C(-3, -1)$

Thus, $(x, y) \rightarrow (-y, x)$

Then shifting horizontally to the right 2 units, we get ΔA'B'C'

Thus,

$(x, y) \rightarrow (-y, x) \rightarrow (x+2, y)$
