Triangle abc is an isosceles triangle in which angle b = angle c and l and m are points on ab and ac respectively such that lm parallel to bc. If angle a = 50 degree find angle lmc

∵ ABC is an isosceles  triangle

∵ m∠b = m∠c

∴ m∠b and m∠c = 180 - m∠a/2

= 180 - 50/2

= 130 /2

= 65°

∵ ∠c and ∠AMI are corresponding angles

∵ m∠AMl = m∠c = 65°  (1)

From (1)

∵ ∠AMC is striaght angle

∴ m∠IMC = 180 - m∠AMI

m∠IMC = 180 - 65

m∠IMC = 115°

Answer = 115°

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
