Answer:
see explanation
Step-by-step explanation:
∠1 and 170° form a straight angle and are supplementary, thus
∠1 = 180° - 170° = 10°
∠1 and ∠3 are vertical angles and congruent , thus
∠3 = 10°
∠2, 15° and ∠3 form a straight angle and sum to 180°, thus
∠2 = 180° - 15° - 10° = 155°
Thus
∠1 = 10°, ∠2 = 155°, ∠3 = 10°
Answer:
1
Step-by-step explanation:
The zeroes or x intercepts are when the line crosses through the x-axis.
In this case you should only have one being (1) because the line only passes the x-axis once. Also by real zeroes it means non -5i #s so nothing with an (i) for imaginary #'s.
Hope this helps.

Volume of a ball = (4/3)πr³
When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³
the volume of air in the larger ball is <span>17182.08 cm³ greater than smaller ball </span>
Answer:
10
Step-by-step explanation:
2x3=6
16/4=4
4x3-(6-4)
6-4=2
4x3-(2)
4x3=12
12-(2)
12-2=10
