In ∆abc the angle bisectors drawn from vertexes a and b intersect at point d. find ∠adb if:
m∠a = α , m∠b = β

The measure angle ADB = 180 - (α/2+ β/2) 

Step-by-step explanation:

measure angle A is α degrees, this means that, the angle bisector divides the angle into two equal angles each of measure α/2 degrees

measure angle B is β degrees, this means that the angle bisector divides the angle into two equal angles each of measure β/2 degrees

In triangle ADB, we know that the sum of all measure of a triangle is 180 degrees and we have measure angle MAB = α/2 degrees and measure angle MBA = β/2 degrees

Therefore,

measure angle ADB = 180 - (α/2+ β/2) 

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

students group

step-by-step explanation:

a person who   joins a party or a seminar can explain his feelings about that particular occasion better more than anyone else.

as bella managed a show for the students in the school and invited students to watch that show

hence

students group will be the best group to survey to find this information
