Answer:
I think Vivek is 20 and his father is 50
Because 30 + 30 equals 60 as he has to be half his age he'll be 30 but that's in 10 years time. you just subtract 30 and 60 by 10 and you'll get 20 and 50

Answer:
65 degrees
Step-by-step explanation:
All angles of a triangle have to add up to 180 degrees. After establishing that, we can see that there are two angles given. 25 degrees and a 90-degree symbol. So if two angles add up to 115 degrees, we can do 180-115=65 to find the angle of C.
Answer:
Step-by-step explanation:
surface area of sphere=4πr²=4π×12²=576π
≈576×3.1416
≈1809.5616 cm²
cost to cover=1809.5616×0.05=$90.47808≈$90.48
