To Prove: ABC is an isosceles triangle.

Construction: Construct a perpendicular bisector from point B to Line segment AC.

Consider triangle BAD and BCD,

(given)

(By the definition of a perpendicular bisector)

Therefore, by Angle Side Angle(ASA) Postulate.

Line segment AB is congruent to Line segment BC because corresponding parts of congruent triangles are congruent.(CPCTC)

Please help on this math question!!

Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= $\sqrt{(7\sqrt{(33)^{2} }- (33)^{2}$

= $\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}$

The side that continues next to 33: x -33

Applying similarity property on right triangles:

$\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}$

$(33)(x-33)=(4\sqrt{33} )^{2}$

$33x-1089=528$

$33x=528+1089$

$x=\frac{528+1089}{33} =49$

Hope this helps
