Question

BP and cp are the bisectors of LB
g LB
and Lc respectively
prove that x=90°+1/2y​

Answer 1

Answer:

To prove L80 L = 90°-1 LA 2

Proof - In A ABC

LA+ LB + LL = 180° Angle Sum Property

LA + 2LCB0 +2LOCB

LA + 2(LLBO + LOLB) - 180 - LA LA + LLRO+ Locb = 180 2

=) ) LA + LLBO + LOCB = 90°- LA 2 In A BOC, LAngle LCBO + LOCB + LBOC= 180 Angle Sum = 90° - LA + LBOL = 180° property

2

Q8) LBOL 180°- 90° +LA 2

= 90° + LA 2

Hence, proved ナ
