<h2><u>Answer:</u></h2>

'?' is <u>88°.</u>

<h2><u>Step-by-step explanation:</u></h2>
  • First, we work out the final angle of the left triangle, which has a total of 180°. To do this we take 40° and 66° from 180°, giving us <u>72°</u>
  • Because there is a straight line along the bottom (which will total 180°), we take both 72° and 56° from 180°, giving us <u>52°</u>, which is the bottom left angle of the right triangle.
  • Finally, to work out '?', we take 52° and 40° from 180° to get our final answer of <u>88°.</u>

the sum of two different numbers x and y is 70 and the differences when the smaller number is subtracted from the larger number
Bad White [126]

Answer:

1000

Step-by-step explanation:

Lets just say x is the bigger number. We can create two equations.

x + y = 70

x - y = 30

If we add these equations together, we get that:

2x = 100

and that

x=50

Plugging x back into any of the equations gets us that y = 20, so xy = 20*50 = 1000
