in triangle ABC, angle b = 45 degree, angle c =55 degree, AD bisects angle A, find angle ADB and Angle ADC

angle a + angle b + angle c = 180 (angle sum property)

a + 45+55= 180

a + 100 = 180

a = 180-100

a= 80

AD bisects angle a

i.e angle ADB= angle ADC

angle ADB + angle ADC = 80

angle ADB + angle ADB =80

2angleADB= 80

angle ADB = 80/2

angle ADB = 40

angle ADB = angle ADC

40 = angle ADC

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
