Answer:

proving question

Step-by-step explanation:

The triangles have been drawn along with the circle and the figure is attached.

In ΔABD and ΔDCA

i) ∠ BAD = ∠ ADC = 90° [ Angle in a semicircle is always 90°]

ii) BD = AC [ both are diameters]

iii) AD = AD [ AD is a common side in both triangle]

Therefore, Δ ABD and ΔDCA are congruent to each other by RHS rule.

Guys I need the answers to number 16

Umnica [9.8K]

#16: Let's clear the fraction on the way to solving this inequality for x. By mult. the given inequality by 2, we'll get -2 (is greater than) x+4. We want x to be positive. So, leave it where it is. Subtract 4 from both sides of this inequality. We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6. What would the graph of that simple inequality look like?

Graph it. (Hint: The graph is a straight dashed line, and you must shade one side of it, but not the other side.
