Step-by-step explanation:
<h3>Given:</h3>
<h3>Prove: </h3>
<h3>Solution:</h3>
m ∠WBX = 180° - m ∠3
m ∠ZAY = 180° - m ∠4
- ∠WBX ≅ ∠ZAY as ∠3 ≅ ∠4 and 180° - m ∠3 = 180° - m ∠4
- BX ≅ AY, given
- BW ≅ AZ, given
ΔWBX ≅ ΔZAY as per SAS postulate
∠W ≅ ∠Z as corresponding angles of congruent triangles
As per above the triangle WTZ is isosceles

Answer:
3. 2x
Step-by-step explanation:
The side ratios of a 30-60-90 triangle are in the ratios ...
1 : √ : 2
The longest side is 2 times the length of the shortest side. If the shortest side is x, the longest side is 2x.

Answer:
The polar form is <em> sinθ = 2 r³cos⁴θ </em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given function y = 2 x⁴
<em>Parametric Form x = r cosθ ....(i)</em>
<em> and y = r sinθ ....(</em>ii)
squaring x² = r² cos ²θ
y² = r² sin²θ
adding x² + y² = r² cos ²θ+r² s in²θ
= r²( cos ²θ+s in²θ)
= r²( 1)
<em> x² + y² = r²</em>
<em> </em>Given function y = 2 x⁴
Now convert into polar form
<em> r sinθ = 2 (r cos θ )⁴</em>
<em> r sinθ = 2 (r )⁴cos θ )⁴ </em>
<em> sinθ = 2 r ³cos⁴θ </em>
