WebThe angle bisector theorem states that the ratio of the length of the line segment BD to the length of segment CD is equal to the ratio of the length of side AB to the length of side AC : and conversely, if a point D on the side BC of ABC divides BC in the same ratio as the sides AB and AC, then AD is the angle bisector of angle ∠ A .
Given a right triangle triangle ABC with C=90^circ, if a=2
WebThe correct option is A32° In Δ ABD,∠ BAD = ∠ DBA = 37 ∘Let ∠ BDA = yy + 37 ∘ + 37 ∘ = 180 ∘y + 74 ∘ = 180 ∘y = 106 ∘In Δ ADC,DC = AC (given in question)∠ ADC = ∠ DAC = (180 ∘ - 106 ∘) = 74 ∘ (Linear pair)∠ DAC = ∠ ADC (Since, DC = AC)Now, x + 74 ∘ + 74 ∘ = 180 ∘x = 32 ∘Hence, the value of x = 32 ∘ ...
