Answer:
the angle of elevation is 12.56°
Step-by-step explanation:
the height of the ramp represents the opposite side and the length of the ramp the hypotenuse
we see that it has (angle, hypotenuse, opposite)
well to start we have to know the relationship between angles, legs and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
we choose the one with opposite and hypotenuse
sin α = o/h
sin α = 5ft / 23ft
sin α = 5/23
α = sin^-1 ( 5/23)
α = 12.56°
the angle of elevation is 12.56°

Step-by-step explanation:
Answer with explanation:
Income earned by my parents in every two weeks = $ 1046.78
In two weeks there are 14 days, so income earned by my parents in 1 day

Income of my parents after a month, if there are 30 days in a month = $74.77 × 30= $ 2243.10
We, will use ,
rule here , which states that , 28% of monthly income of my parents, should be used for monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.
28% of $2243.78
= $ 628.26 (Approx)
So,my parents, monthly housing expense should not exceed ≥ $ 628.26
Answer:
x = 3, y = 3
Step-by-step explanation:
x = -5x -18
5x + 18 = -x
6x + 18 = 0
6x = 18
x = 3
