Answer:
a should be 45
b should be 90
c should also be 45
Step-by-step explanation:
I know this because 180-135=45 for a
since c is also 45, beside c should be 135.
which means those angles are congruent.
since a triangle equals 180 degrees all together 180-45-45=90
so b is 90
correct me if im wrong
Answer:
I'm sry I don't understand but good luck mate
Step-by-step explanation:
Solution:
we are given that
Both circle Q and circle R have a central angle measuring 140°. The area of circle Q's sector is 25π m^2, and the area of circle R's sector is 49π m^2.
we have been asked to find the ratio of the radius of circle Q to the radius of circle R?
As we know that
Area of the sector is directly proportional to square of radius. So we can write

4 rock, 2 reggae, 2 country...total of 8
P(1st song is reggae) = 2/8 which reduces to 1/4
P(2nd song is reggae) = 1/7
P(both events happening) : 1/4 * 1/7 = 1/28
Answer:
