Question

Geometry Triangles.....

Answer 1

Answer:

4

Step-by-step explanation:

since the triangle is isosceles, the vertical line splits the base into two equal halves. the triangle is now 3 - x - 5.

use Pythagorean theorem $a^{2} +b^{2} =c^{2}$, where c is the hypotenuse and a and b are the other side lengths

$5^{2} =3^{2} +x^{2}$

25=9+$x^{2}$

$x^{2}$ = 16

x = $\sqrt{16}$

x = ±4

since a measure of distance cannot be negative, x = 4, not -4.
