Answer:
2.55 cm
Step-by-step explanation: If the diameter is 5.1 cm, ten you have to divide that by 2 in order to get the radius.
5.1/2=2.55
- Use the Law of SInes to find the measure of angle C:
(sinC)/c = (sinA)/a
sincC = c(sinA<span>)/a
C = sin</span>⁻¹(c·sinA / a)
Plugging in numbers:
C = sin⁻¹(83·sin(31) / 44<span>)
= </span>sin⁻<span>¹(0.97155)
= 76.3°
- We know that the sum of the internal angles of a triangle is 180°, therefore:
B = 180 - (A + C)
= 180 - (31 + 76.3)
= 180 - 107.3
= 72.7°
- Therefore the corret answer is C: angle B is 72.7°</span>
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.
