Answer:
I think x is 1/2.
Step-by-step explanation:
Because the triangles are similar, you can set 9x + 1 = x + 5. Subtract x and 1 from both sides to get 8x = 4. divide and you get x = 1/2.
(double check me though.)
This inequality is always true
32. The absolute value of a number x (|x|) will always be positive. It just means how far the number is from 0 on the number line.
Answer:
1. Perpendicular
2. Isosceles
3. Never
Step-by-step explanation:
1. AC ⊥ BD because diameter of a square are perpendicular bisector of each other.
2. In Δ AOB , By using pythagoras : AB² = OA² + OB² .......( 1 )
In Δ COB , By using pythagoras : BC² = OC² + OB² ..........( 2 )
But, OA = OC because both are radius of same circle
So, by using equations ( 1 ) and ( 2 ), We get AB = BC ≠ AC
⇒ ABC is a triangle having two equal sides so ABC is an isosceles triangle.
3. The side can never be equal to radius of circle because the side of the square will be chord for the circle and in a circle chord can never be equal to its radius
