Question

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

Explanation:

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 $t$

$t=180^{\circ}-(56^{\circ} + 72^{\circ})$
$t=180^{\circ}-128^{\circ}$
$t = 52^{\circ}$

Answer:

$52$
