What is the value of x<br><br> 1/5 = 25/x
Mama L [17]
First getting x as a numerator rather than a denominator. Then grouping like terms by moving 5 from the left side to the right. Work below:
\frac{1}{5} = \frac{25}{x} \\  \frac{1}{5}*x = \frac{25}{x}*x\\ \frac{1}{5}x = 25\\\frac{1}{5}x * 5 = 25*5\\x=125

In spherical geometry, all points are points on the surface of a sphere. A line is a circle on the sphere whose diameter is equa
mamaluj [8]

Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.

Step-by-step explanation:

For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.

in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.

Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.

Two triangles in sphere that are similar must be congruent.
