Answer: 39 degrees

Step-by-step explanation: The angle sum of a triangle is 180 degrees so we take 102 from 180.

180-102=78

Since the two angles are the same then we just divide 78 by 2

78/2=39

Answer:

∠E ≈ 37°

Step-by-step explanation:

Using the Sine Rule in ΔEFG, that is

\frac{26}{sinE} = \frac{42}{sin102} ( cross- multiply )

42 × sinE = 26 × sin102° ( divide both sides by 42 )

sinE = \frac{26(sin102)}{42} ≈ 0.6055..

E = sin^{-1} (0.6055 ) ≈ 37°
