X=72
Step-by-step explanation:
216/3= 72
The distance across the lake, a is 611 yards
<h3>Right angle triangle:</h3>
Right angle triangle have one of its angles as 90 degrees. Therefore, the side a can be found using trigonometric ratios,
Therefore,
tan 47° = opposite / adjacent
tan 47° = a / 570
cross multiply
a = 570 tan 47°
a = 570 × 1.07236871002
a = 611.250164714
a = 611 yards

Answer:
not congruent
Step-by-step explanation:
angles are not equal
C = $7s
independent variable ie the changing variable is s
dependent variable ie the non changing variable is c
Answer:
y = - 
x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = 
= 
= -
the line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = - x + 5 ← equation of line
