Question

use your understanding of triangles to answer the questions below. 8. in triangle efg, the measure of angle fge is 35°, and the measure of angle gef is 62.2°. what is the measure of angle efg? a. 117.2° b. 83.2° c. 82.8° d. 27.8°
d. triangle lmn is shown below. what is the measure of ∠l? summarize today’s lesson:

Explanation:

Step1: Sumar ángulos conocidos (Pregunta 8)

$\angle FGE + \angle GEF = 35^\circ + 62.2^\circ = 97.2^\circ$

Step2: Restar de 180° (Pregunta 8)

$\angle EFG = 180^\circ - 97.2^\circ = 82.8^\circ$

Step3: Sumar ángulos conocidos (Pregunta 9)

$\angle M + \angle N = 52.7^\circ + 69.1^\circ = 121.8^\circ$

Step4: Restar de 180° (Pregunta 9)

$\angle L = 180^\circ - 121.8^\circ = 58.2^\circ$

Answer:

1. C. $82.8^\circ$
2. $58.2^\circ$
