$\bigtriangleup ABC \: has\: a\: right\: angle\: C\\\Rightarrow \hat{A}+\hat{B}=90° \Leftrightarrow 3x + 2x = 90\Leftrightarrow 5x = 90\Leftrightarrow x = 18\\\Rightartow \hat{A}=3\times 18=54°,\hat{B}=2\times 18=36°$

Answer:

c(<B=73)

Step-by-step explanation:

The two congruent sides have equal base angles

$34 + 2x = 180$

$2x = 180 - 34$

$2x = 146$

$\frac{2x}{2} = \frac{146}{2}$

$x = 73$
