Answer:
s = 4
Step-by-step explanation:
Note that the triangle has 2 congruent base angles, both 45°
This means the triangle is isosceles with congruent legs, then
s = 4
Answer:CD = x = 4 units
Explanation:We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:

W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5
Substitute in the above proportionality and solve for x as follows:

4x = 20 - x
5x = 20
x = 4
Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units
Hope this helps :)
Answer:

Step-by-step explanation:
ANSWER
A.

EXPLANATION
The given equation is

This equation is already in the form:

This is called the slope-intercept form.
The slope is

and the y-intercept is 3.
The correct answer is A.
In a situation where the line is not given in the slope intercept form, then you must rewrite in this form before comparing.
