Answer:
x=27
Step-by-step explanation:
3x+9 is a right angle because 3x+9 + a right angle make a straight line
3x+9 +90 = 180
Subtract 90 from each side
3x+9 = 90
We now can solve for x
3x+9-9 = 90-9
3x = 81
Divide each side by 3
3x/3 = 81/3
x=27
Answer:
Area of square = Composite Area - Area of Triangle
= 32.5 - 7.5 = 25
Area of square = 25 square feet.
Formula for area of square = s²
s² = 25
s = √25
s = 5
Length of each side of square = 5 feet.
Answer:
8
Step-by-step explanation:
Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as
1070=180(n-2) where n is the number of sides required here.
Making n the subject of the formula then following step by step
Therefore, the shape is octagon and it has 8 sides.
Answer:
the answer is 17
Step-by-step explanation:
6×3-1
= 17
Ok
Probability (the point will be on unshaded part) = area of unshaded part / area of the circle.
= pi r^2 - s^2
-------------- where r = radius of circle and s = length of the side of the square.
pi r^2
