Please help me with this question i don't get it

Answers

ok so im not going to completely solve it but i will basically give u the answer
180 - 121 = 59
the sum of angles in a triangle is 180 so
180-59 = 121
the rest of the angles are going to sum up to 121 so
121=7x + (6x-9)
from here just do basic algebra
121+Q=180(exterior angle of triangle)
Q=180-121
Q=59

7x+6x-9+59=180(anglesum property)
13x+50=180
13x=130
x=10


6x-9=60-9
=51

7x=7*10
=70



Ans=59,70,51

Check:51+59+70=180
