Answer:

C = 15

Step-by-step explanation:

Both (7c-7)° & (6c-8)° if get combined will form a straight angle i.e. 180° because both the angles lie on the same line. So,

$7c - 7 + 6c - 8 = 180°$

$= > 13c - 15 = 180°$

$= > 13c = 180 + 15 = 195$

$= > c = \frac{195}{13} = 15$

Angle ZYX=180-115=65
in triangle sum of angles =180
so
4k+5+6k+10+65=180
10k+80=180
10k=180+80=260
k=260/10
k=26
