Question

What is the value for x?

x = ___

Answer 1

Greetings!

Answer:

x = 5

Explanation:

Because this is an isosceles triangle, as indicated with the parallel lines on lines AB and BC, angles A and C are the same, because both lengths are the same.

This can mean that angle B can be discovered by adding the two angle sizes together:

73 + 73 = 146

To find the angle of B, you can subtract the above value from 180 (total angle size in a triangle:

180 - 146 = 34

So angle B = 34

This also means that:

6x + 4 = 34

Isolate the 6x by moving the +4 over to the other side, making it a negative:

6x = 34 - 4

6x = 30

Simply divide both by 6 to find x:

`(6x)/(6) = (30)/(6)`

x = 5

So the value of x = 5!

Hope this helps!
