Answer 2

hi,

180 =(3x+13)+(x-8)+x

when x=35, that means that angle A is

3(35)+13
105+13
=118

Answer 3

sum of angles =180
find x and then 3x+13

Answer 4

Well, I am here.
Sorry for late.


All we know that the sum of all interior angles measures for ant triangle is 180

Agree?

Answer 5

\[\Large (x)+(x-8)+(3x+13)=180\]
\[\Large 5x+5=180\]
\[\Large 5x=175\]
\[\Huge\color{red}{x=35}\]


After that can you plug x-value into the measure of the angle A??
