Answer:

In SAS similarity theorem if two sides of one triangle are proportional to two sides of another triangle and angle between them are congruent then the triangle are similar.

Step-by-step explanation:

From SAS similarity theorem-two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional.

Now, we check the similarity from SAS , if two sides of first triangle are proportional to two sides of another triangle and angle between them are congruent.

From triangle UVW and triangle XYZ

Use sides UV and UW in Δ UVW and XY and XZ in ΔXYZ .

$\frac{UV}{XY}=\frac{UW}{XZ}$

and angle between them .

A map has a scale of 1/8 of an inch is equal to 1/4 of a mile. What is the unit rate of inches per mile

algol [13]

Answer:

1 inch per 2 miles.

Step-by-step explanation:

1/8 of an inch = 1/4 of a mile.

To solve the rate of inch per mile, multiply 8 to both sides (to make inch = 1)

(1/8)(8) = 1

(1/4)(8) = 8/4 = 2

The unit rate of inches per mile is 1 inch per 2 miles.

I will mark you brainliest if its correctly

zheka24 [161]

Step-by-step explanation:

sina = -√3/2

$\cos(a) = \sqrt{1 - { \sin(a) }^{2} }$

$= \sqrt{1 - { (\frac{ - \sqrt{ 3} }{2}) }^{2} }$

$= \sqrt{ \frac{4 - 3}{4} }$

$= \sqrt{ \frac{1}{4} }$

=±1/2

Since, π<a<3π/2

cos a = -1/2

$\tan(a )= \frac{ \sin(a) }{ \cos(a) }$

$\tan(a ) = \sqrt{3}$

If p(x)=x^3-3x^2-x+3 and p(3)=0, what is a factor of p(x)

IRISSAK [1]

<h3>Answer: x-3</h3>

Since p(3) = 0, this means x = 3 plugs into p(x) to get 0

We can write p(x) as p(x) = (x-3)q(x) where q(x) is some other polynomial that multiplies with (x-3) to lead to x^3-3x^2-x+3

Let's plug in x = 3 and see what happens

p(x) = (x-3)q(x)

p(3) = (3-3)q(3)

p(3) = 0*q(3)

p(3) = 0

No matter what the result of q(3) was, it doesn't matter because it multiplies with 0 to get 0.

The general rule is: if p(k) = 0, then x-k is a factor of p(x). This is a special case of the remainder theorem.
