Answer:
tan A= 8/15
Step-by-step explanation:
- draw triangle where A and B are legs and C is hypotenuse
- A=8 and C=17, meaning that you need to find B by using Pythagorean theorem (a^2+b^2=c^2)
- 8^2+b^2=17^2
- 64+b^2=289
- b^2=225
6.
7. b=15
8. tan= opposite/adjacent
9. tan A=8/15
Answer:
15% of 20 is 3
Step-by-step explanation:
15% is 15/100 which can reduce to 3/20.
3/20*20
The 2 20's cancel out.
All you have left is 3.
15% of 20 is 3
Hope this helps!
