Answer:

T=139°

Step-by-step explanation:

First we solve for x

Here is our equation

(21x+13)+(3x-1)+(4x)=180

Combine like terms

28x+12=180°

28x=168°

x=6°

T=21x+13,T=126+13

T=126+13, T=139

Triangle ABC has vertices of A(-6, 7), B (4, -1), and C (-2, -9). What is the length of the median from angle B?
jeka94
Coordinates of the midpoint of AC:
M ( (-6-2) / 2) , ( 7-9 ) /2 ) = ( -4, -1 )
d ( BM ) = √ ( 4 + 4 )² + ( -1+ 1 )²
d ( BM ) =   √  8 ²  =√ 64 = 8
The length of the median from angle B is 8.
