Answer:

$y=40\°$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles triangle

$AB=AC$

$5x=40\°$

$x=8\°$

The sum of the internal angles of a triangle is equal to $180\°$

Find the value of y

$(2y+20)\°+2(40\°)=180\°$

$2y=180\°-20\°-80\°$

$2y=80\°$

$y=40\°$

Answer:

Taylor is closest to the table

Step-by-step explanation:

I divided 64, 4, 7, 0.615, and 001 01 and got 1.876 so i figured out that that is half of 64%. So that gave me an idea that Taylor was closest to the table.

Elevator 1 moved up 15 feet from the ground level. Its position is labeled as +15. Elevator 2 moved down 6 feet from the ground

The ground level is to be the zero level. When the elevator moves above the ground level, it is moving towards the positive integer and when the elevator moves below the ground level, it is moving towards the negative integer.

Elevator 2 moved down 6 feet from the ground level hence its position is labelled as $-6$
