Answer:
-2x + 4
Step-by-step explanation:
Answer:
x ≈ 36.1
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan61° = 
= 
( multiply both sides by 20 )
20 × tan61° = x , then
x ≈ 36.1 ( to the nearest tenth )
So, say your # was 6,234,578. you would go to the seven and look to the number next to in, so 8, and if the neighbor is 5 or bigger, you make the number, in this case a 7 an 8. Last, you make all the other #s after the one you rounded 0. So the answer would be:
6,234,570.0
