Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π

Step-by-step explanation:
Answer:
∠AZ = ∠BX
The two triangles are equivalent triangles
Step-by-step explanation:
Flowchart proofs are organized with boxes and arrows. The statements given are written in the box and the reason of that statement is written just below the box. Every statement if flowchart proof complements other statement.
∠AZ = ∠BX
The two triangles are equivalent triangles.
When f(X) is at 7, (X) will also be 7 bc the slope is a 1/1
