Step-by-step explanation:
1. m(angle A) is 90 degrees............[ tangent drawn from the centre of the circle is always perpendicular to the circle]
2.m(angle C) is also 90 degrees....[ tangent drawn from the centre of the circle is always perpendicular to the circle]
3. m(angle 1) is 57 degrees, angle A is 90 degrees, .....(given)
m(angle 4) + m(angle 1) + angle A = 180 ...............[ sum of measures of a triangle is always 180 degrees]
m(angle 4) = 180 - ( 57 + 90)
= 33 degrees
4. m(angle 3 ) is 63 degrees, m(angle C) is 90 degrees, .........[given]
m(angle 3) + m(angle 2) + angle C = 180 ...............[ sum of measures of a triangle is always 180 degrees]
m(angle 2) = 180 - ( 63 + 90)
= 27 degrees
total number of tiles is 6. the number of yellow or purple tiles i 1+3 = 4.
So the probability of a yellow or purple tile is 4/6=2/3
Answer:
2/5
Step-by-step explanation:
Out of the available options on the spinner, only 1 and 5 are factors of 25.
=> Outcomes = 2
=> Total outcomes = 5
P (factor of 25) = 2/5
Hope it helps.
