Which would prove that ΔABC ~ ΔXYZ? Select TWO options.

gulaghasi [49]

Answer:

$\frac{BA}{YX}=\frac{BC}{YZ}$ , ∠C ≅∠Z

$\frac{AC}{XZ}=\frac{BA}{YX}$ , ∠A≅∠X

$\frac{BA}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}$

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

so

In this problem

The corresponding sides are

BA and YX

BC and YZ

AC and XZ

The corresponding angles are

∠A and ∠X

∠B and ∠Y

∠C and ∠Z

so

$\frac{BA}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}$

and

∠A≅∠X

∠B≅∠Y

∠C ≅∠Z

therefore

$\frac{BA}{YX}=\frac{BC}{YZ}$ , ∠C ≅∠Z

$\frac{AC}{XZ}=\frac{BA}{YX}$ , ∠A≅∠X

$\frac{BA}{YX}=\frac{BC}{YZ}=\frac{AC}{XZ}$

Regular pentagonal tiles and triangular tiles are arranged in the pattern shown. The pentagonal tiles are all the same size and

First of all you have to find the missing measurements. The actual measurements for the angles in the hexagon are not given, but they give you an expression. You have to solve for x first so that you can plug it in and find the angle measurement. You have to equal the two sides that are given to you like this: 20x+48=33x+9. You solve for x and then plug it into each angle measurement. This should give you 108. Since it is a regular hexagon all of the sides are equal. If you look at the angle at the top of the hexagon you'll see two triangles and the angle. Since it lies on a straight line, it is all equal to 180. You already have the angle measurement of the hexagon and are missing the triangles. So 180-108=72. 72 is the missing part of the angle. You divide this by 2 in order to find each triangle angle measurements. the answer is 36 degrees.

The point (1, 4) lies on a circle that is centered at (1, 1). Which statements are correct? Check all that apply.

Semenov [28]

the circle's radius is 3 units

the point (- 2, 1 ) lies on the circle

the equation of a circle in standard form is

(x - a)² + (y - b)² = r²

where (a, b) are the coordinates of the centre and r is the radius

the radius is the distance from the centre to the point (1, 4 ) on the circle

using (1, 4) and (1,1) in the distance formula, then

r = √(1 - 1 )² + (1 - 4)² = √(0 + 9) =√9 = 3 ⇒ r² = 9

(x - 1 )² + (y - 1 )² = 9 ← equation of circle

substitute the given points into the equation and if equation is true then they lie on the circle

(- 2, 1 ) : (- 2 - 1 )² + (1 - 1 )² = 9 + 0 = 9 ← true

Hence (- 2, 1 ) lies on the circle

(3, 3 ) : (3 - 1 )² + (3 - 1 )² = 4 + 4 = 8 ≠ 9

(3, 3 ) does not lie on the circle
