Ok, so perimeter is the outside of the shape added all together. This rectangle is 5 units tall and 14 units long. To find perimeter add all of the sides together 5(left)+5(right)+13(top)+1(bottom)=36 the perimeter is 36 units
Answer from: Quest
< coa = 150 ( given)
as ba and bc are tangents
so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre
Aroulette wheel has 38 slots in which the ball can land. two of the slots are green, 18 are red, and 18 are black. the ball is equally likely to land in any slot. the roulette wheel is going to be spun twice, and the outcomes of the two spins are independent. the probability that it lands one time on red and another time on black in any order is(a) 0.5 (b) 0.25 (c) 0.4488 (d) 0.2244
Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
