(4x+9)(3x+5)
=12x^2+20x+27x+45
=12x^2+47x+45
4,927 would be the correct answer you just do it on calculator
Answer:
The green dots in this picture would be where the points go:
Answer:
14.93°
Step-by-step explanation:
Using trigonometry :
From the diagram attached :
Angle of elevation = x
To obtain the value of x
Tan x = opposite / Adjacent
Tan x = 8 / 30
Tan x = 0.266666
x = tan^-1(0.26666)
x = 14.93°
Therefore, the angle of elevation is 14.93°
