<span>1.a coefficient is a number multiplying a variable so if 5 is multiplying x then that would make it the coefficient
2. a term is a number and a variable multiplying or being multiplied , so it would be 2x,and 4y.
3.a variable term is a unknown number multiplying or being multiplied, so it would be c and d
4.a constant term is a term that is not </span>accompanied by a variable or is being multiplied by a number. so it would be 2, and 14

Eric reflected parallelogram ABCD across the x-axis. If angle A is 125° and angle B is 55°, what is the degree measurement of an

Sauron [17]

The measures of the angles don't change when you translate a figure, because the entire figure is moving as a whole. Imagine having a paper parallelogram, moving it around and flipping it over. Not even dilations would change these angles (for reasons that can be pretty easily visualed but not really proven until geometry)

$m\angle A'=125\°$

Question 20

Andrej [43]

The distance between the bottom of the lighthouse and the boat is 77.6m.

<h3>What is the distance between the bottom of the lighthouse and the boat?</h3>

The lighthouse and the boat would form a right triangle. The height would be the height of the lighthouse. The distance between the top of the lighthouse and boat would be the hypotenuse. The distance between the bottom of the lighthouse and the boat would be the base.

In order to determine the required distance, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where:
a = length
b = base
c = hypotenuse

125² = 98² + b²

b² = 125² - 98²

b = √(25² - 98² )

b = 77.6m
