Question

angle abc similar to triangle d e f and angle is equals to angle D 90 degrees find the measure of Angle B + angle f​

Answer 1

∠B  +  ∠F = 90°

Step-by-step explanation:

Δ ABC  ≈ Δ DEF

=> ∠A = ∠D  = 90°

    ∠B = ∠E

   ∠C = ∠F

Now in Δ ABC

∠A +   ∠B  +  ∠C  = 180°

Now putting ∠A = ∠D  = 90°

=> 90° +   ∠B  +  ∠C  = 180°

=>  ∠B  +  ∠C  = 90°

now puuting     ∠C = ∠F

=> ∠B  +  ∠F = 90°

Hence ∠B  +  ∠F = 90°
