Chlorine is added in the water treatment process because it kills off all of the bacteria and bad things inside of the water that may not be seen. It doesn’t necessarily “filter” it out, it’s just because the organisms living inside of it die because of the chemical element.

Sandra drew an isosceles triangle that has an angle that measures 46 degrees. Which could be the measures of the other two angle
kipiarov [429]

Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

or

46, 67 and 67°
