Question

1) Given ∆ABC - ∆DEF, if /E= 35º and /A= 45° then find 2B.
A) 45°
B) 35°
C) 25°
D) 40°
​

Answer 1

Step-by-step explanation:

When two triangles are similar, their corresponding angles are equal

$\Delta ABC \sim \Delta D E F$

$\implies \angle B = \angle E = 35^{\circ}$

$\implies 2 \angle B = 2 \times 35^{\circ} = 70^{\circ}$
