Answer:
Length of RU is 20 units.
Step-by-step explanation:
In ΔRSt and ΔRUT,
ST ≅ TU [Given]
RT ≅ RT [Reflexive property]
∠RTS ≅ ∠RTU [Both the angles are the right angles]
ΔRTS ≅ ΔRTU [By SAS property of congruence]
Therefore, RS ≅ RU [By CPCTC (corresponding parts of the congruent triangles are congruent]
8x = 6x + 5
8x - 6x = 5
2x = 5
x = 2.5
Length of RU = (6x + 5)
= 6(2.5) + 5
= 15 + 5
= 20
Length of RU is 20 units.
Whats the question that you have and remember theres always google
Answer: -2sin³x
Step-by-step explanation:
cos ( x + y ) = cosx*cosy - sin y*sinx (1)
if x = y (1) could be express as: cos (2x) = cosx*cosx -sinx*sinx
cos 2x = cos²x -sin²x
Then sin(x)*cos2(x) − sin(x) ⇒ sinx * ( cos²x - sin²x ) - sinx
multiplying sinx*cos²x -sin³x -sinx
sinx (commom factor sinx (cos²x -sin²x -1) but 1-cos²x = sin²x
or -1 +cos²x = -sin²x ⇒sinx( -sin²x -sin²x) ⇒sinx (-2sin²x)
-2sin³x
