Question

What is the value for y?



Enter your answer in the box.

y =

Answer 1

The value of Y is 40

Explanation:

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

Answer 2

`y=28`

Explanation:

This is an isosceles triangle, which are a type of triangles that have a pair of equal sides. Having at least one pair of equal sides allows isosceles triangles to have well-known features. For example, the pair of angles adjacent to the base have the same value because they oppose equal sides within the same triangle.

So, in this case:

`34=(x-5)`

Solving for x:

`x=34+5=39`

Thus:

`\angle B=x-5 =39-5=34`

So, since the sum of the interior angles of a triangle is equal to 180:

`\angle A + \angle B + \angle C =180\\\\34+34+4y=180`

Solving for y:

`4y=180-68\\\\4y=112\\\\y=(112)/(4) \\\\y=28`

And:

`\angle C = 4y= 4*28 =112`
