Answer: 21.414
Step-by-step explanation:
1. add a zero after 4.3
2. multiply 0 by 8= 0
3. multiply 3 by 8= 24
4. carry the 2 over the 4
5. multiply 8 by 4 and then add 2= 34
6. first row= 3440
7. add a zero to the ones place
8. multiply 9 by 0= 0
9. multiply 9 by 3=27
10. carry the two over the 4
11. multiply 9 by 4 and add 2= 38
12. second row= 38700
13. add 2 zeros to the ones and tens place
14. multiply 4 by 0=4
15. multiply 4 by 3= 12
16. carry the one over the 4
17. multiply 4 by 4 and add one=17
18. third row=172000
19. add up all the rows= 214140
20. place the decimal point 4 units to the left of the last number
21. answer= 21.414
Hi there! For this question, you need to know the ratio of sine and cosine.
- sinA = opposite/hypotenuse
- cosA = adjacent/hypotenuse
Define A = angle
opposite and adjacent side changes only if we focus on another angle.
From the picture, if we focus on angle S, the opposite would be 36. But if we focus on angle R (flip to make RT as base), see that the opposite would be 14.
Answer
- sinS = 36/42 = 6/7
- sinR = 14/42 = 1/3
- cosS = 14/42 = 1/3
- cosR = 36/42 = 6/7
The bold one is simplest form while the non-bold is non-simplest.

Hope this helps, and Happy Learning ! :)
Answer:
Step-by-step explanation:
∠Q = 180-∠T = 89°
∠S = 360-∠T-∠Q-∠R = 360-91-89-27 = 153°
The annswer is A. Square inscribed in a circle.
