Step-by-step explanation:
A=1/2(B1+B2)h is a trapezoid
A=1/2bh is a triangle
A=bh is a parallelogram
And A=Pir2 is a circle
70 palm trees are on that street
To find the length of the ladder, you need to do Pythagorean theorem.
50^2 + 30^2 = x^2
2500 + 900 = x^2
x^2 =3400
x= square root of 3400
58.31 OR 10 root34
To find the angle:
tan theta = opposite/adjacent
50/30 = 5/3
theta = tan inverse of 5/3
= 59.04
