THERE ARE 7 ELEMENTS
Our aim is to calculate the Radius so that to use the formula related to the area of a segment of a circle, that is: Aire of segment = Ф.R²/2
Let o be the center of the circle, AB the chord of 8 in subtending the arc f120°
Let OH be the altitude of triangle AOB. We know that a chord perpendicular to a radius bisects the chord in the middle. Hence AH = HB = 4 in
The triangle HOB is a semi equilateral triangle, so OH (facing 30°)=1/2 R. Now Pythagoras: OB² = OH² + 4²==> R² = (R/2)² + 16
R² = R²/4 +16. Solve for R ==> R =8/√3
OB² = OH² +
C is the hypotenuse, so the pythagorean theorem used would be: 15²=13²+6². 225=169+36, but 169+36 does not equal to 225, therefore the triangle is not a right triangle
Answer:
A. None of the answers are correct
Step-by-step explanation:
∠3 is a verticle angle to ∠1
linear pair means they add up to 180
complementary mean they add up to 90
