The perimeter of equilateral triangle DEF is 24 cm.
<h3>
Triangle</h3>
A triangle is a polygon with three sides and three angles. Types of triangles are<em> equilateral, isosceles, obtuse, scalene</em>.
Given that triangle ABC is equilateral, also triangle DEF is equilateral.
DE = DF = EF = 10 - 1 - 1 = 8 cm
Perimeter of DEF = 8 + 8 + 8 = 24 cm
The perimeter of equilateral triangle DEF is 24 cm.

option C is correct.
Step-by-step explanation:
Answer:
me, what's the question so I can see how to figure out the answer
Answer:
y = -x + 9
Step-by-step explanation:
✔️Find the slope using (9, 0) and (7, 2):
Slope (m) = -1
✔️Find the y-intercept (b):
The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9
✔️Substitute m = -1 and b = 9 into y = mx + b
Thus,
y = -1(x) + 9
y = -x + 9
