here's the solution,

we know that, sum of measures of each interior angle of a triangle = 180°

Figure 1.

=》

$40 + 32 + 9x + 9 = 180$

=》

$81 + 9x = 180$

=》

$9x = 180 - 81$

=》

$x = \frac{99}{9}$

=》

$x = 11$

Figure 2. 

=》

$42 + 63 + 4x + 15 = 180$

=》

$120 + 4x = 180$

=》

$4x = 180 - 120$

=》

$4x = 60$

=》

$x = \frac{60}{4}$

=》

$x = 15$

Figure 3.

=》

$45 + 45 + 3x - 21 = 180$

=》

$3x + 69 = 180$

=》

$3x = 180 - 69$

=》

$3x = 111$

=》

$x = \frac{111}{3}$

=》

$x = 37$
