Answer:
steps below
Step-by-step explanation:
1. 1 + 1/2*(n-1) : 3, 7/2, 4, 9/2
2. 1 + 1/3*(n-1): 7/3, 8/3, 9/3, 10/3
3. 3/2 + 1/2*(n-1): 4, 9/2, 5
4. 1, 4, 16, 19, 76...79, 316, 319, 1276 ...
x ≈ 34.28
Using the tangent ratio in the right triangle
tan29° = = ( multiply both sides by x )
x × tan29° = 19 ( divide both sides by tan29° )
x = ≈ 34.28 ( to the nearest hundredth )
The answer is m∠R = 48.59 °
45%
9/20. 20* 5= 100. 9*5=45. 45/100=45%
Answer:55
