Step-by-step explanation:
1..x=110/2. ( inscribed angle is half of central angle)
2..given,
in triangle DFE
angleDFE=angle DAE ( inscribed angle on same arc are equal)
angle DFE=55°
angle EDF= angle FED (base angle of isosceles triangle r equal)
now,
angle EDF+angleDFE+angle FED =180°{ sum of angle of triangle)
z+z+55=180°
2z=180-55
z=125/2
z=62.5°
3.. y=90°{ angle at circumference of circle by center is 90°}
hope it helps.

Answer:
(12, 9)
Step-by-step explanation:
I am assuming it was rotated about the origin.
180 degrees clockwise would give the point ((9, 12).
Then if this point is roated 90 degrees anti-clockwise it would end up at the point (12,9)
<h3>The actual height of building is 37.5 feet</h3>
<em><u>Solution:</u></em>
Given that,
The drawing of a building shown below has a scale of 1 inch to 30 feet
1 inch = 30 feet
The drawing of the building of this problem has the height of 1.25 inches and base of 0.75 inches
<em><u>Thus actual height is given as:</u></em>
height = 1.25 inches

<em><u>The actual base is given as:</u></em>
base = 0.75 inches

Thus actual base is 22.5 feet
