Answer:

1+cos^2(2A)=(1−cos2(2A))+2cos^2(2A)

=sin^2(2A)+2(cos^2A−sin^2A)^2

=(2sinAcosA)^2+2(cos^4A−2cos^2Asin^2A+sin^4A)

=2(cos^4A+sin^4A)

Triangle SRQ undergoes a rigid transformation that results in triangle VUT. 2 right triangles with identical side lengths and an

nikdorinn [45]

Answer:

The true statements are 2 and 3.

Step-by-step explanation:

Triangle SRQ undergoes a rigid transformation that results in triangle VUT

So, ΔSRQ ≅ ΔVUT

So, point S will map to point V, point R will map to point U and point Q will map to point T.

According to the previous, We will check the statements:

1) SQ corresponds to VU. Wrong because SQ corresponds to VT

2) ∠R corresponds to ∠U. True

3) UV corresponds to RS. True

4) ∠S corresponds to ∠T. Wrong because ∠S corresponds to ∠V

5) QS corresponds to RS. Wrong because QS corresponds to TV

So, The true statements are 2 and 3.

2) ∠R corresponds to ∠U

3) UV corresponds to RS.
