find the number of degrees in the third angle of the triangle. the measure of the missing angle is (square^{circ}). the figure is not drawn to scale.

find the number of degrees in the third angle of the triangle. the measure of the missing angle is (square^{circ}). the figure is not drawn to scale.

Answer

Explanation:

Step1: Record la suma de los ángulos internos de un triángulo

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

Step2: Establece una ecuación

Sean los ángulos 43°, 98° y (x). Entonces (43 + 98+x=180).

Step3: Resuelve la ecuación para (x)

Primero suma 43 y 98: (43 + 98=141). Luego (x = 180-141). (x=39)

Answer:

39
