Answer: x = 33 degrees
Step-by-step explanation:
The given triangle is a right angle triangle.
From the given right angle triangle,
The length of the hypotenuse of the right angle triangle is 19
With x degrees as the reference angle,
The length of the adjacent side of the right angle triangle is 16
To determine x, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse side. Therefore,
Cos x = 16/19 = 0.842
x = Cos^-1(0.842)
x = 33 degrees
Answer:
115.48
Step-by-step explanation:
This shape can be split into two distinct shapes
Two halves of a semi circle, and a rectangle in between
Circle:
Putting both halves of the semi circle together will give you a full circle. The diameter of the circle is given (7m).
The area of a circle is A = π 
The radius, r, is half of the diameter, so 7 / 2 = 3.5m
A = π 
A = π * 
A = 38.38
Rectangle:
The area of a rectangle is A = h b
The height, h, is known at 7m
The base, b, can be found by removing the length from the dot to the end of the semi circles. This length is the radius of the semi circles, 3.5m
Removing the radius from the total length given
18 - 3.5 - 3.5 = 11m
The base is 11m
A = h b
A = 7 * 11 = 77
Total Area = Circle area + Rectangle area
Total Area = 38.38 + 77 = 115.48
7n - 25/ 3

Answer:
5y+10
Step-by-step explanation:
The best way to rewrite this equation is to use the distributive property.
5y+10
Or, we can just use the commutative property to switch the numbers around, but I recommend the distributive.
5(2+y)
Hope this helps!
