Answer:
Angle A = 60°
Step-by-step explanation:
As the sum of the interior angles are added up to 180 °
<A + <C + <B = 180°
Given that,
<A = (2x)°
<C = x °
<B = 90°
Therefore,
[tex]2x +x+90=180\\[/tex]
[tex]3x+90=180[/tex]
[tex]3x=180-90[/tex]
[tex]3x=90[/tex]
[tex]\frac{3x}{3} =\frac{90}{3}[/tex]
[tex]x = 30[/tex]
Now let's solve for angle A
[tex]<A=2x[/tex]
[tex]2*30[/tex]
60°
