Answer:
a = 68°, b = 112°, c = 68°
Step-by-step explanation:
112° is a vertical angle to the one with the line through it, therefore they are equal. The angle opposite to b is equal to the one opposite to 112°. b and 112° are vertical angles, so b = 112°. a is a supplementary angle to b, so b + a = 180°. 112° + a = 180°, so a = 68°. c is vertical to a, c = 68° as well.

Answer:
r = 3.
Step-by-step explanation:
16 = 10 + √(3r + 27)
√(3r + 27) = 6
Square both sides:
3r + 27 = 36
3r = 36 - 27 = 9
r = 3.
Check the result:
Left side of the equation = 16
Right side = 10 + √(9 + 27)
= 10 + √36 = 16
