Answer:
Solution,
x+12+8x-2=180° (Linear pair)
or, 9x+10=180°
or, x+10=180/9
or, x=20-10
x=10
The length of MT
=8x-2
=8×10-2
=80-2
=78
hope it helps you
Step-by-step explanation:
x+12+8x-2=180(being straight line)
or,9x+10=180
or,9x=180-10
or,9x=170
or,x=170/9
x=18.88
now,
MT=8x-2
=8(18.88)-2
=149.04
