Answer:

(a)x=128 degrees

(b) $\angle APD\neq 116^\circ$

Step-by-step explanation:

$\angle ABD+\angle CBD =180^\circ$ (Linear Postulate)\\\angle ABD+116^\circ =180^\circ\\\angle ABD=180^\circ-116^\circ\\\angle ABD=64^\circ$

(a) Now:

$\angle AOD=2 \times \angle ABD$ (Angle at the centre is twice the angle at the circumference)\\x=2 \times 64^\circ\\x=128^\circ$

(b)

$\angle APD=2 \times \angle ABD$ (Inscribed Angle Theorem)\\\angle APD=2 \times 64^\circ\\ \angle APD=128^\circ$

$\angle APD\neq 116^\circ$

Triangle ABC is reflected over the line y = x to produce triangle A'B'C'. What will be the coordinates of A'? A (2,−1) B (−2,−1)

zheka24 [161]

Answer:

when P(x,y) is reflected in y=x line then

P(x,y) = P(y,x)

A(2, -1)= A(-1, 2)

B(-2, -1) = B(-1, -2)

C(2, 1)= C(1, 2)

D(1,2)= D(2,1)
