Step-by-step explanation:

Triangles DPA and DMU are similar

DP/DM = PA/MU

3.75/10 = 4.5/MU

MU = 4.5×10/3.75

MU = 12

Area = ½ × (4+10) × 12

½ × 14 × 12

Prove the identity: cos(3x) + cos(x) = 2cos(2x)cos(x)

Jet001 [13]

$cos \alpha +cos \beta =2\cdot cos \frac{ \alpha + \beta }{2} \cdot cos \frac{ \alpha - \beta }{2}\\-----------------\\\\ \alpha =3x\ \ \ and\ \ \ \beta =x\\\\$

$L=cos \alpha +cos \beta =cos(3x)+cos(x)\\\\\Rightarrow\ \ \ 2\cdot cos \frac{ \alpha + \beta }{2} \cdot cos \frac{ \alpha - \beta }{2}=2\cdot cos \frac{3x+x}{2} \cdot cos \frac{3x-x}{2} =\\\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ =2\cdot cos \frac{4x}{2} \cdot cos \frac{2x}{2} =\\\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ =2\cdot cos(2x)\cdot cos (x)=R$
