Two vertical angles are formed. These angles are also equal to each other.
Answer:
The area of the sector shown is 4.75 pi
Step-by-step explanation:
First we have to know what fraction of the total circle that part represents
for that we divide 45 by 360
45/360 = 1/8
now we calculate the area of the circle and divide it by 8
a = ( π * 6² ) / 8
a = ( π * 36 ) / 8
a = π * 4.75
a = 4.75 pi
The sides are in the ratio 1 : 1 : sqrt2 where sqrt 2 = hypotenuse
so if the length of one of the legs is 2 cm the hypotenuse will be of length 2 *sqrt 2 cms.
b ) sin 45 = 1 / sqrt2 = sqrt2 / 2
c) if the 2 legs of triangle are both 2 cms area will be 1/2* 2* 2
-35 angle degree I hope it helps
