For this case, we convert the mixed numbers into fractions:
Now, rewriting the expression in three equivalent forms we have:
Answer:
Answer:
∠AEX = 70°
Step-by-step explanation:
From the diagram
AX ≅ BX
BY ≅ CY
AZ ≅ CZ
∠XAE = 20°
A circumcenter has equal distant from vertices of the triangle since radii of circles are congruent.
For the given figure, the midpoints is at Z, X, Y
And the perpendiculars also occur at Z, X, Y
∠Z = 90°
∠X = 90°
∠Y = 90°
∠XAE ∠AXE +∠AEX= 180° (sum of angles in a triangle)
∠AXE = ∠X = 90°
20° + 90° +∠AEX= 180°
110° +∠AEX= 180°
∠AEX = 180°-110°
∠AEX = 70°
Answer:
C) 314 feet.
Step-by-step explanation:
We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.
The distance around the track would be equal to circumference of circle.
, where r represents radius of circle.
Since we have been given across distance, so it will be diameter of track.
To find radius we will divide across distance by 2.
Upon substituting our given values in circumference formula, we will get:
Therefore, the distance around the track is 314 feet and option C is the correct choice.
