Answer:
<h2>x = 5√3</h2><h2>y = 15</h2>Step-by-step explanation:
Look at the picture.
ΔABC, ΔDBA and ΔDAC are the triangles 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.
Therefore
<h3>in ΔDAC:</h3>DC : AD : AC = 1 : √3 : 2
If AC = 10, then DC = 10 : 2 = 5 and AD = x = 5√3
<h3>in ΔDBA:</h3>AD : BD : AB = 1 : √3 : 2
If AD = 5√3, then AB = 2 · 5√3 = 10√3 and BD = y = 5√3 · √3 = 5 · 3 = 15

Answer:
x = 5
Step-by-step explanation:
Given equation as:
= 1
now,
writing each side as power of 2
2⁰ = 1
therefore,
= 2⁰
also, we know the property that , when the number having the same bases gets divided , the powers of the number gets subtracted
therefore,
= 2⁰
now for the equality the power of 2 both sides should be equal
thus,
⇒ 2x-(x+5) = 0
or
⇒ 2x = x + 5
or
⇒ 2x - x = 5
or
⇒ x = 5
