Aquadrilateral has angles that measure 56°,97°,136° what is the measure of the fourth angle

The interior angles of a quadrilateral add up to 360 degrees, always.

To find the missing angle, we simply need to add the angles we know, then subtract from 360.

56 + 97 + 136 = 289

360 - 289 = 71

The missing angle is equal to 71 degrees.

(-1,-0.5)

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
