Answer:

x= 116°

y= 127°

Step-by-step explanation:

x... The angle subtended at the centre is twice the angle subtended at the cicumfernce by the same arch

y.... Angle in a cyclic quadrilateral add up to 180°

hence 180-53=127

Suppose Tommy walks from his home at (0, 0) to the mall at (0, 7), and then walks to a movie theater at (5, 7). After leaving th

For this case, what we must do is find the distance between each ordered pair.
For this, we use the formula of distance between points.
We have then:
$d = \sqrt{(x2-x1)^2+(y2-y1)^2}$

For (0, 0) and (0, 7):
$d1=\sqrt{(0-0)^2+(7-0)^2}$
$d1=\sqrt{(0)^2+(7)^2}$
$d1=\sqrt{0+49}$
$d1=\sqrt{49}$
$d1=7$

For (0, 7) and (5, 7):
$d2=\sqrt{(5-0)^2+(7-7)^2}$
$d2=\sqrt{(5)^2+(0)^2}$
$d2=\sqrt{25+0}$
$d2=\sqrt{25}$
$d2=5$

For (5, 7) and (5, 0):
$d3=\sqrt{(5-5)^2+(7-0)^2}$
$d3=\sqrt{(0)^2+(7)^2}$
$d3=\sqrt{0+49}$
$d3=\sqrt{49}$
$d3=7$

before returning home the total distance is:
$d1 + d2 + d3 = 7 + 5 + 7

d1 + d2 + d3 = 19$

Answer:
before returning home Tommy walks about 19 blocks

Am I getting it right?

So far your getting all of them right. But, maybe next time upload a better picture because it’s hard to see what you wrote.
