Answer:
∠BCO = 55°
Step-by-step explanation:
The sum of all the angles in a triangle is always 180°, so we need to subtract 90° and 35° from 180° to get ∠BCO.
180° - 90° - 35° = 55°
x=27
27/3+5=14
27' by 18'

Answer of Part A is 243 Lunches
Answer of Part B is 850.50$
c. 80
cos x = sin(x-70)
cos x = cos [90-(x-70)]
cos x = cos (90-x +70)
cos x = cos 160 -x
x= 160-x
2x = 160
x =80
