I believe 9, is it one of your options?
Answer:
342.24 units²
Step-by-step explanation:
The area of one of the 8 triangular sections of the octagon is ...
A = (1/2)r²·sin(θ) . . . . . where θ is the central angle of the section
The area of the octagon is 8 times that, so is ...
A = 8·(1/2)·11²·sin(360°/8) = 242√2
A ≈ 342.24 units²
Answer:
second option
Step-by-step explanation:
The slopes of perpendicular lines have a product of -1. The slope of this line is 3 from the graph so the slope of our line will be -1/3. We know the slope of the line and a point (F, G) that belongs to the line so we can use point-slope form.
Point-slope form: y - y₁ = m(x - x₁) and we know that m = -1/3 and (x₁, y₁) = (F, G) so the answer is y - G = -1/3(x - F).
Answer:
No , it is not a right angle triangle
Step-by-step explanation:
according to the pythagoras theorem in right angled triangle sum of square of two sides is equal to the square of it's hypotenuse.
using pythagoras theorem
a^2 + b^2 = c^2
9^2 + 16^2 = 25^2
81 + 256 = 625
337 = 625
since sum of square of two smallest sides of a triangle is not equal to the square of it's hypotenuse it can be concluded that the given figure does not form right angle triangle.
Answer:
3/7
Step-by-step explanation:
6/7 ÷ 2 = 6/14 as simplified as 3/7 in fraction form.
