Answer:
56.25°
Step-by-step explanation:
cos x° = b/h = 15/27 = 5/9
x° = cos^(-1) (5/9) = 56.25°
Answer:
y=-4/1x-13
Step-by-step explanation:
5-1/2-3
5-1 ( 4)
2-3 (-1)
y=-4/1x+b
5=-4/1(2)+b
5=-8+b
b=-13
y=-4/1x-13
Hope this helped, have a Wonderful Day!!
The distance between ladder and bottom of the slide is 4.9 meters.
Step-by-step explanation:
Given,
Height of ladder = 1 m
Length of slide = 5 m
The ladder will serve as perpendicular and slide will serve as hypotenuse.
The distance from bottom of the slide to ladder will be base.
a = 1
c = 5

Taking square root on both sides

Rounding to the nearest tenth
b = 4.9 meters
The distance between ladder and bottom of the slide is 4.9 meters.

Answer:
A
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 9, - 4) and r =
⇒ r² = (
)² = 5
(x + 9)² + (x + 4)² = 5 → A
