Answer:
Step-by-step explanation:
3 sinθ=3 cos 2θ
sin θ=cos 2θ
sinθ=1-2sin² θ
2sin²θ+sin θ-1=0
2sin²θ+2sinθ-sinθ-1=0
2sin θ(sin θ+1)-1(sin θ+1)=0
(sin θ+1)(2 sin θ-1)=0
sin θ=-1=-sin 90=sin (180+90)
θ=270
or sin θ=1/2=sin 30,sin (180-30)
θ=30,150
solution set is {30,150,270}
Answer:
6.5
Step-by-step explanation:
If M is the midpoint of PQ, PM is congruent to MQ. Midpoint means middle. So, the midpoint divides PQ in half. PQ = 13, and 13/2 = 6.5.
Answer:
-11
Step-by-step explanation:
-14+3=-11
Answer:
A
Step-by-step explanation:
The three sides are marked properly to show congruency. The way they are placed (orientation) does not matter. They are congruent by SSS.
No angles are marked and that lets out B C D and there is no right angle anywhere so you can't say E.
There is enough information to say SSS
