a )

Sum of the interior angles of any triangle equals 180° .

Thus :

$angle \: A + angle \: B + angle \: C = 180°$

$35° + 3(x+2)° + 52° = 180°$

$35° + 3x + 6° + 52° = 180°$

$3x + 93° = 180°$

Subtract sides 93°

$3x + 93° - 93° = 180° - 93°$

$3x = 87°$

Divide sides by 3

$\frac{3x}{3} = \frac{87}{3}$

$x = 29°$

b )

$angle \: C = 3 ( x + 2 ) °$

$angle \: C = 3 ( 29+ 2 ) °$

$angle \: C = 3 ( 31 ) °$

$angle \: C =93 °$
