If a transformation is an isometry, how would you describe the relationship between the preimage and the image ?

1 answer:

4 0

The inverse image or preimage of a particular subset S of the codomain of a function is the set of all elements of the domain that map to the members of S. Image and inverse image may also be defined for general binary relations, not just functions.

Answer:

There are two statements that are true:

B. QR = 5.9 cm

D. Measure of angle R = 47 degrees

Step-by-step explanation:

1. Let's recall that if ΔVWX ≅ ΔPQR, then:

VW ≅ PQ

WX ≅ QR

PR ≅ VX

therefore, QR is 5.9 cm and not 4.5 cm

2. Let's recall that if ΔVWX ≅ ΔPQR, then:

∠V ≅ ∠P

∠W ≅ ∠Q

∠X ≅ ∠R

therefore, measure of ∠R is 47° and not 28°

There are two statements that are true:

B. QR = 5.9 cm

D. Measure of angle R = 47 degrees

Find the length of side x in simplest radical form with a rational denominator.

schepotkina [342]

Answer:

x = 2√3

Step-by-step explanation:

The sides of a 30-60-90 triangle are always in the ratio 1:√3:2.

The length of the side opposite the 90° angle is 4, so the length of the side opposite the 30° angle is 2 and the length of the side opposite the 60° angle is 2√3.

x = 2√3
