Step-by-step explanation:
The distance formula between two points:
Substitute the coordinates of the points.
If a ≤ b < c are the sides of the right triangle, then
a² + b² = c²
used for a ≥ 0.
therefore ΔABC is a right triangle.
A circle is centered on Point B. Points A, C, and D lie on it’s circumference. If Angle ADC measures 61 Degrees, what does Angle
ABC measure?

The equation that matches the given situation is . So, after two moves, Eric's elevation changed
meters above.
We know that in mathematics, subtraction means removing something from a group or a number of things. What is left in the group gets smaller when we subtract. The minuend is the first element we use. The subtrahend is the part that is being removed. The difference is the portion that remains after subtraction.
Assume that "negative" means climbing down and "positive" means climbing up. We must locate the elevation change in this area.
Given that Eric climbed straight down meters. So we can write
.
Again Eric climbed straight up meters. So, we can write
.
Then the change =
=
=
=
=
=
=
=
Therefore, the equation that matches the given situation is . So, after two moves, Eric's elevation changed
meters above.
