Answer:

To prove a triangle is isosceles, it can be used the distance formula to see if at least two sides are congruent.

Step-by-step explanation:

An isosceles triangle is a triangle in which two sides are equal in length. The sides are called equal sides, and the last side unequal to them is called the base. By definition, every regular triangle is also isosceles, but the converse is not true.

If a triangle has two equal sides, then these sides are called the lateral sides, and the third side is called the base. The angle formed by the sides is called the vertex angle, and the angles, one of the sides of which is the base, are called the corners at the base.

A triangle with two equal sides has one axis of symmetry, which passes through the vertex angle and the middle of the base. This axis of symmetry coincides with the bisector of the vertex angle, the median drawn to the base, the height drawn from the vertex corner and the middle perpendicular.

Lines AB and AC are equal so you set up an equation like so...
4x + 1 = 2x + 23
Subtract 1 from both sides.
4x = 2x + 22
Subtract 2x from both sides.
2x = 22
Divide.
x = 11
Now you need to plug in 11 into 3x - 8.
3(11) - 8
= 33 - 8
= 25
So BC is 25.
I hope this helps love! :)

c) There are 32 students in a class. If the ratio of the number of boys and girls is 5:3, find the number of boys and girls. ​
stepladder [879]

Answer:

The no. of boys = 20

The no. of girls = 12

Step-by-step explanation:

Ratio of no. of boys to girls = 5 : 3

[5 multiplied with something, and 3 multiplied with something, added together makes 32.Thus, that something = x]

5x + 3x = 32

= 8x = 32

=x = 32÷8 = 4

5x = 5 x 4 = 20

3x = 3 x 4 = 12
