By definition, let m be the slope a line, then m can be calculated by the following equation:

Given that (x1, y1) and (x2, y2) are known points of the line. By reflecting all the points of the line across the line y = x
2 is the greatest comun factor
A.
y = 15 tan(30°)
y = 15/√3 ≈ 8.66 ft
b.
y = 15 tan(40°) ≈ 12.59 ft
c.
A = 1/2 base x height ≈ 129.9 ft² and 188.8 ft² for 30° and 40°

Answer:
30000+1000+80+4+0.5
Step-by-step explanation:
Expanded notation can be defined as to rewrite the numbers to show their place values
For example in the given question 3 is at the tenth thousand place, 1 is at the thousand'th place,8 at tenth and 4 at unit place so the solution for the question is given below:
30000+1000+80+4+0.5
3×10000+1×1000+8×10+4×1+(5×1÷10)
