Question
the diagram shows a triangle. what is the value of t? t = □°
Step1: Record la suma de ángulos internos de un triángulo
La suma de los ángulos internos de un triángulo es 180°.
Step2: Escribir la ecuación
$t + 56^{\circ}+72^{\circ}=180^{\circ}$
Step3: Resolver para $t$
$t=180^{\circ}-(56^{\circ} + 72^{\circ})$
$t=180^{\circ}-128^{\circ}$
$t = 52^{\circ}$
