In a ΔXYZ, XO is the median and $XO - \frac{1}{2}YZ$. If ∠YXO = 30°, then what is the value of ∠XYZ? |
15° 90° 30° 60° |
30° |
According to the question, in triangle XOY, As XO is median, So ⇒ YO = OZ ⇒ and as XO = \(\frac{1}{2}\) YZ, then ⇒ XO = YO + OZ In triangle XYO, ⇒ XO = OY So the triangle XYO is an isosceles triangle ⇒ So, \(\angle\)YXO = \(\angle\)XYO = \({30}^\circ\) ⇒ and \(\angle\)XYO = \(\angle\)XYZ ⇒ \(\angle\)XYZ = \({30}^\circ\) Therefore, the required value is \({30}^\circ\) |
