Answer:
x = 80
Step-by-step explanation:
Because supplementary angles are 180 degrees so the only possible value of x is 80 degrees because 100 + 80 = 180
Answer:
<h2>254.5 in^2</h2>
Step-by-step explanation:
Given that the circumference of the frame is 56in
we can proceed to obtain the radius of the frame
we know that
circumference= 2πr
56= 2*3.142*r
56= 6.284r
divide both sides by 6.284
r= 56/6.284
r=8.9
approximately radius is 9in
therefore the area of the mirror that is largest would be
Area= πr^2
Area= 3.142*9^2
Area= 3.142*81
Area= 254.5 in^2
The largest area is 254.5 in^2
Answer:
Option (3)
Step-by-step explanation:
From the figure attached,
AB and CD are two chords intersecting at O.
m∠AOD = 37°
m∠AOC + m∠AOD = 180° [Since these angles are supplementary angles]
m∠AOC = 180° - 37°
= 143°
By the theorem of intersecting chords,
Measure of angle formed is the half of the sum of measures of the arcs intercepted by the angle and vertical angle.
m∠AOC =
143° =
143° = x
Therefore, Option (3) will be the answer.
