Question

the diagram shows a triangle. what is the value of b? b = □°

Explanation:

Step1: Record la suma de ángulos internos de un triángulo

La suma de los ángulos internos de un triángulo es 180°.

Step2: Escribe una ecuación

$b + 35^{\circ}+36^{\circ}=180^{\circ}$

Step3: Resuelve para b

$b=180^{\circ}-(35^{\circ} + 36^{\circ})$
$b = 180^{\circ}-71^{\circ}$
$b = 109^{\circ}$

Answer:

$109$
