Is WXY ~ ZYV? Justify your answer. The image is - 1

Answers

Answer 1
Answer:

Answer: C. Yes, WXY ~ ZYV with a scale factor of 9:8.

Step-by-step explanation:

In the given picture, we have two triangles Δ WXY and Δ ZYV in which

\angle {X}=\angle{Y}               [Right angle]

\angle {W}=\angle{Z}  

Therefore, by AA- similarity postulate, we have

\triangle{WXY}\sim\triangle{ZYV}

The scale factor is given by :-

k=(WX)/(ZY)=(XY)/(YV)=\frac{WY]{ZV}

\Rightarrow k=(18)/(16)=(6.75)/(6)=(22.5)/(20)=(9)/(8)

Hence,  \triangle{WXY}\sim\triangle{ZYV} with scale factor of 9:8 .

Len is baking a square cake for his friend wedding. When served to the guests, the cake will be cut into square pieces 1 inch on the side. The cake should be large enough so that 121 guests get one piece. How long should each side of the cake be?

Answers

You would just need to take the square root of 121 since it is square. So:

√121= 11 inches per side

Final answer:

Len must bake a square cake that's 11 inches on each side to satisfy 121 guests with square pieces of cake.

Explanation:

To calculate the length of each side of the cake, we will use the concept of square root. The square root of a number gives the length of the side of a square whose area is that number. The number of guests, who will each receive one square piece of cake, is the area of the cake in square inches. So, we need to calculate the square root of 121, which is the number of guests.

Step 1: Write down the number of guests, 121.

Step 2: Calculate the square root of the number from step 1. The square root of 121 is 11.

Therefore, the length of each side of the cake should be 11 inches.

A point P(3,4)is reflected in the x-axis, then rotated by 90 degrees clockwise about the origin.What are the coordinates of the image of P?

Answers

Answer:

(-4, -3)

Step-by-step explanation:

When a point is reflected in the x-axis, the x-coordinate does not change, and the y-coordinate becomes negative:

  • (x, y) → (x, -y)

Therefore, if point P(3, 4) is reflected in the x-axis, then:

  • P' = (3, -4)

When a point is rotated90° clockwise about the origin, it produces a point that has the coordinates (y, -x):

  • (x, y) → (y, -x)

Therefore, if point P'(3, -4) is rotated 90° clockwise about the origin, then:

  • P'' = (-4, -3)

Can you use the sss postulate or the sas postulate to prove ABC and AED are congruent ?

Answers

Answer:

Neither SSS nor SAS apply.

Step-by-step explanation:

SSS (Side-Side-Side)-

If three pairs of sides of two triangles are equal in length, then the triangles are congruent.

SAS (Side-Angle-Side)-

If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent.

It given in the picture that,

  1. AC = AD (Side)
  2. BC = DE (Side)
  3. m∠BAC = m∠EAD (Angle)

So, ΔABC and ΔAED will not be congruent by either SSS or SAS.
