The measurement of angle x is 40°. these two triangle are congruent so their sides share the same length and their angles share the same degrees
Answer:
Perimetro = 4 cm + 7 cm + 12 cm
= 23 cm
Step-by-step explanation:
Answer: #13 you need to know that the sides are equal. #14 (7,6)
Step-by-step explanation: #14 in picture
The red line is a reflection across the x-axis, so the correct option is d.
<h3>
How to write the equation for the red line?</h3>
First, we know that the black line is represented by y = f(x). Here, we can see that the red line is given by a reflection around the x-axis.
This reflection only changes the sign of the right side, then we get that the function of the red line is:
g(x) = -f(x)
Then we can write this as:
y = g(x) = -f(x) = -1*f(x)
If we divide both sides by -1, we get:
y/(-1) = f(x)
Like in option d, so that is the correct one.
