Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
Triangle ABC would remain the same because a dilation generally preserves the measure of an angle.
<h3>What is scale factor?</h3>
A scale factor simply refers to a ratio of two (2) corresponding side lengths or diameter in two (2) similar geometric figures such as triangles.
In this exercise, you're required to construct a dilation of triangle ABC that is centered at B with a scale factor of 2 by using a compass and straightedge.
In conclusion, triangle ABC would remain the same because a dilation generally preserves the measure of an angle.

Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
s ×
= 4
( divide both sides by
)
s = 4 → A
