Answer:
17.5
Step-by-step explanation:
The following data were obtained from the question:
Angle R = 105°
Side R = r
Side S = 15
Side T = 6
The value of r can be obtained by using cosine rule formula as shown below:
inding sides:
r² = s²+ t² – 2st cos(R)
r² = 15² + 6² – 2 × 15 × 6 × cos105°
r² = 225 + 36 – 180 × cos105°
r² = 261 + 46.587
r² = 307.587
Take the square root of both side
r = √307.587
r = 17.5
Therefore, the value of r is 17.5
1. 22/25
2. -1 1/4
3. -1 7/10
4. 1 5/6
5. 1 2/3
Student that play,
baseball: 18
Both= 30
basketball= 17
5/3 and 6/2 because the pattern shows that it adds one to the numerator while it deducts one from the denominator.
