Name a pair of supplementary angles.
a. angle a e b and angle c e d
b. angle a e b and angle b e d
c. angle a e c and angle b e d
d. angle b e a and angle c e b

B.angle AEB and angle BED.

Step-by-step explanation:

We are given that a diagram .

We have to find a pair of supplementary angles.

Supplementary angles:The pair of angles whose sum is 180 degrees is called supplementary angles.

From given diagram

Hence, option B is true.

B.angle AEB and angle BED.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
