Answer: x=60 degrees

Step-by-step explanation: This triangle is an equilateral triangle, meaning all angles are equal. Since a triangle is 180 degrees total, 180 degrees/3 angles= 60 degrees each angle.

Given $dc = 7$, $cb = 8$, $ab = \frac{1}{4}ad$, and $ed = \frac{4}{5}ad$, find $fc$. Express your answer as a decimal.

Pachacha [2.7K]

A ↔ B ↔ C ↔ D ↔ E ↔ F

$\frac{1}{4} AD$ 8 7 $\frac{4}{5} AD$ ???

AB + BC + CD = AD <em>segment addition postulate</em>

$\frac{1}{4} AD$ + 8 + 7 = AD

$\frac{1}{4} AD$ + 15 = AD

AD + 60 = 4AD

60 = 3AD

20 = AD

AB = $\frac{1}{4} AD$ = $\frac{1}{4}(20)$ = 5

DE = $\frac{4}{5}AD$ = $\frac{4}{5}(5)$ = 4

CD + DE + EF = CF <em>segment addition postulate</em>

7 + 4 + EF = CF

11 + EF = CF

Answer: 11 + EF

Note: You did not provide any info about EF. If you have additional information that you did not type in, calculate EF and add it to 11 to find the length of CF.
