A corner of a rectangle is cut, creating a trapezoid.
forsale [732]

Answer:

the last option of 135°.

Step-by-step explanation:

The total degree of the rectangle is 360°. But it was sliced, so with the remaining measurements, subtract each of them from 360°.

90°+90°+45°+x°=360°

225°+x°=360°                 add all of the values on the left side, then subtract 225 on both sides to solve for the value of x°.

x°=135°

Scrat [10]

Step-by-step explanation:

the probability of A working is 60% or 0.6, so the probability it does not work is 40% or 0.4.

the probability of B working is 90% or 0.9, so the probability it does not work is 10% or 0.1.

plan 1

it is the probabilty that either A works, or (if it is not working) B works.

0.6 + 0.4×0.9 = 0.6 + 0.36 = 0.96

plan 2

either B works, or (if it is not working) A works

0.9 + 0.1×0.6 = 0.9 + 0.06 = 0.96

both plans have the same success probability.
