Answer:
EF = 68°
Step-by-step explanation:
If 2 chords of a circle are congruent then the corresponding arcs are congruent.
The central angle FDG is equal in measure to the arc that subtends it
arc FG = 68°
Given EF ≡ FG , then
arc EF ≡ arc FG, so
arc EF = 68°
Answer:
∠ QRS = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4n - 9 + 5n - 18 + 90 = 180, that is
9n + 63 = 180 ( subtract 63 from both sides )
9n = 117 ( divide both sides by 9 )
n = 13
Thus
∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°
∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°
If you would like to simplify the expression 22 * (32 - 42), you can do this using the following step:
22 * (32 - 42<span>) = 22 * (-10) = - 22 * 10 = - 220

The correct result would be - 220.
