In kite WXYZ, mZWY = 41° and mXYW = 11°<br><br><br> What is mWZY?

olchik [2.2K]

Answer:

128°

Step-by-step explanation:

In kite WXYZ, WY and XZ are longer and smaller diagonals respectively.

Longer diagonal bisects the opposite angles.

$\therefore m\angle ZYW =m\angle XYW$

$\because m\angle XYW = 11\degree... (given)$

$\therefore m\angle ZYW =11\degree$

$In\: \triangle WYZ$

$m\angle ZYW + m\angle ZWY + m\angle WZY=180\degree$

$11\degree + 41\degree+ m\angle WZY=180\degree$

$52\degree+ m\angle WZY=180\degree$

$m\angle WZY=180\degree - 52\degree$

$\purple{\bold {m\angle WZY=128\degree}}$

Help picture below problem 5

Anna35 [415]

$\angle F+ \angle E = 180^{\circ}\\\\ \implies \angle F + 164^{\circ} = 180^\circ\\\\\implies \angle F = 180^\circ - 164^\circ\\\\\implies \angle F= 16^\circ$

Factor 9x^3y-25xy^3 completely.

pickupchik [31]

$9x^3y-25xy^3=xy(9x^2-25y^2)=xy\underbrace{\left[(3x)^2-(5y)^2\right]}_{use\ a^2-b^2=(a-b)(a+b)}\\\\=\boxed{xy(3x-5y)(3x+5y)}$
