Find the value of x. The image is of regular triangle with base 14 and one side 15, angle between them is divided equally by a segment to meet the opposite side dividing it in to length x and 7 from top vertex to base respectively.

A. 15.0
B. 13.5
C. 9.0
D. 7.5

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

yes

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
