eeeeeAnswer:
Step-by-step explanation:
Apply the Pythagorean theorem
a^2 + b^2 = c^2
a = 5, b = 13.
5^2 = 25, 13^2 = 169
25 + 169 = 194
square root 194 = 13.928, rounded to nearest foot = 14 ft.
The minimum ladder length required to reach the top of the wall = 14 ft.
Answer:
cos34°
sin56°
Step-by-step explanation:
Sin(2x+42)= sin90-(3x+13)
Sin(2x+42) = sin(90-13-3x)
Sin(2x+42) = sin(77-3x)
2x + 42 = 77-3x
5x. = 35
X = 7
If x = 7
cos(3x+13) = cos((3*7)+13)
cos(3x+13) = cos(21+13)
cos(3x+13)= cos34
And
sin(2x+42) = sin((2*7)+42)
sin(2x+42)= sin (14+42)
sin(2x+42) = sin56
