Question

(4) In the figure below, Mis the mid point of the line AB.
Compute the other two angles of triangle ABC.​

Answer 1

Answer:

angle ACB = 80 ; angle BAC = 50 ; angle ABC = 50

Step-by-step explanation:

CM perpindecular bisect the triangle ABC,

therefore , angle ACM = angle MCB

in ΔACM , angle A = 50 , M = 90 ,C =x

angle (50 + 90 + x) = 180

x = 40

angle ACM = 40

angle ACB = 40 + 40 = 80

inΔABC

angle ACB + angle BAC + angle ABC = 180

50 + 80 + angle ABC = 180

angle ABC = 50

Answer 2

Answer:

angle ACB = 80 ; angle BAC = 50 ; angle ABC = 50

Step-by-step explanation:

CM perpindecular bisect the triangle ABC,

therefore , angle ACM = angle MCB

in ΔACM , angle A = 50 , M = 90 ,C =x

angle (50 + 90 + x) = 180

x = 40

angle ACM = 40

angle ACB = 40 + 40 = 80

inΔABC

angle ACB + angle BAC + angle ABC = 180

50 + 80 + angle ABC = 180

angle ABC = 50
