A = 3
b = 10
70/(10) + 5(3) - 2(10)
70/10 = 7
5(3) = 15
2(10) = 20
7 + 15 - 20 =2
2 is your answer
hope this helps
Answer
As per the statement:
Height of the building(h)= 30 feet
Angle of elevation
= 41°
We have to find the distance of observer from the base of the building.
Using tangent ratio:

You can see the diagram as shown below.
Opposite side = height of the building = 30 feet.
Adjacent side = distance of observer from the base of the building = x (let)
Then;

0.86928673781 = 
By cross multiply we have;

Divide by 0.86928673781 both sides we get;
x = 34.51 m
Therefore, the distance of observer from the base of the building is 34.51 m
The club made 5 pies. If each pie is cut into 5 slices, and there are now 40 slices after the cafeteria donated, divide 40 by 5, which is 8. Subtract the 3 that the cafeteria donated.
If sum of numbers (a) +(b) is 1419 and
(a) and (b) are <span>neighbors , whe have:
a + b = 1419 and b-a = 1;
<=> </span>a + b = 1419 and <span>a = b-1 ;
so we have b-1 + b = 1419 <=> 2b = 1420 <=> b=710 and a = 709
Answer: 710 and 709
