Answer:

$12\sin{(2\theta)}\cos{(\theta)}$

Step-by-step explanation:

The appropriate trig identity is ...

$\sin{a}+\sin{b}=2\sin{\left(\dfrac{a+b}{2}\right)}\cos{\left(\dfrac{a-b}{2}\right)}$

Here, you have a scale factor of 6 and a=3θ, b=θ. Filling in these values gives ...

$6\sin{3\theta}+6\sin{\theta}=12\sin{\left(\dfrac{3\theta+\theta}{2}\right)}\cos{\left(\dfrac{3\theta-\theta}{2}\right)}\\\\=12\sin{(2\theta)}\cos{(\theta)}$

Find the measure of angle Y and the length of side XY of parallelogram WZYZ.

Sveta_85 [38]

XY=WZ=28. (Opposite sides of a parallelogram are equal)

Angle Z=angle C=105
=>angle Y=180-105=75. (Co-interior angles are supplementary)
Hope this helps u...!!
