Tell whether the angle measures can be those of a triangle.

Mathematics

babunello [35]2 years ago

No.

The 3 angles of a triangle need to equal 180 degrees.

The sum of the 3 given angles is greater than 180 ( 160 + 20 + 20 = 200) so it cannot form a triangle.

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.

housing: 900/4500 = 0.2 = 20%

transportation: 650 / 4500 = 0.14 = 14%

utilities: 120/4500 = 0.026 = 2.6% ( round to 3% maybe)

food: 475/4500 = 0.105 = 10.5% (round to 11% maybe)

savings: 1600 / 4500 = 0.355 = 35.5% (round to 36% maybe)

Student Loan: 270 / 4500 = 0.06 = 6%

Other expenses: 485 / 4500 = 0.107 = 10.7% (round to 11% maybe)



 You didn't say if they needed to be rounded so I gave you the options on the ones that may need it.
