Question

Find the following ot is urgent​

Answer 1

Answer

x = 60°

y = 30°

BC = 15cm

Answer 2

Answer:

angle x = 180° - 120° = 60° ( adjacent angles )

Angle B = 90° ( Right angle )

Angle y :

Angle X + Angle B + Angle Y = 180° ( sum of angles of triangle )

60° + 90° + Angle Y = 180°

150° + Angle Y = 180°

Angle Y = 180° - 150° = 30°

Angle X = 60°

Angle Y = 30°

AB = 20cm AC = 25cm

BC² = AC² - AB²

BC² = 625 - 400

BC² = 225

BC = √15 × 15

BC = 15cm

* There is no Angle sign to be put...so I have written the word Angle
