From the description given for the triangle above, I think the type of triangle that is represented would be a right triangle. This type of triangle contains a right angle and two acute angles. In order to say or prove that it is a right triangle, it should be able to satisfy the Pythagorean Theorem which relates the sides of the triangle. It is expressed as follows:
c^2 = a^2 + b^2
where c is the hypotenuse or the longest side and a, b are the two shorter sides.
To prove that the triangle is indeed a right triangle, we use the equation above.
c^2 = a^2 + b^2
c^2 = 20^2 = 10^2 + (10sqrt(3))^2
400 = 100 + (100(3))
400 = 400
Answer:
i think this is the correct answer
Step-by-step explanation:
Simplifying
8x + -7y = 23
Solving
8x + -7y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
8x + -7y + 7y = 23 + 7y
Combine like terms: -7y + 7y = 0
8x + 0 = 23 + 7y
8x = 23 + 7y
Divide each side by '8'.
x = 2.875 + 0.875y
Simplifying
x = 2.875 + 0.875y
Answer:
V = 452.2 in³
Step-by-step explanation:
V = Pi(r²)h
V = 3.14(6²)(4)
V = 452.16 in³

Your answer is 6.
To find the area of a triangle, you will times height by base and divide by then divide by two. In this case the height is 22 and the base is 10. 22 times 10 is 220. You then would divided 220 by two, making your answer 110 cm squared.
