Question

Find the length of MT

Answer 1

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

Answer 2

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
