This triangle is obtuse( as it's one angle is greater than 90°) as well as isosceles (as it's two sides are equal).
Answer:
f=10
Step-by-step explanation:
I don't know a formula for this but I can see that <CRE is a 90° angle so 7f+2f=90 and if f=10 7f=70 and 2f=20 which fits
No i dint think it is 2×8-4=12 and 8 is not equal to 12 :)
My guess is 3.109126351029605. I am not 100% sure its the correct answer you are looking for. Good luck!
